From Grand Slam legends to record-breaking champions, who is the greatest tennis player of all time? Vote and rank them based on career achievements, dominance, and legacy.
What counts: 'Best' is judged by Grand Slam singles titles, weeks at world No.1, career longevity, and overall impact on the sport. Figures are approximate and sourced from widely reported career statistics as of recent seasons.
He turned himself from a brittle, allergy-plagued talent into the most complete returner and mental tactician the game has seen, grinding down Federer and Nadal in their primes to claim the head-to-head and the record books. With 24 Grand Slam singles titles and the most weeks at world No.1 in history, his career is an argument that ruthless self-optimization can out-legend even genius. The Rod Laver Arena meltdown-turned-triumphs and the 2011 season that redefined 'unbeatable' seal his case as the statistical GOAT, whatever your heart says.

The kid in sleeveless shirts who turned Roland Garros into his personal fiefdom, Nadal's 14 French Open titles are a number so absurd it reads like a typo, built on a topspin forehand that made clay-court tennis feel like geological erosion. He dragged Federer into brutal five-set wars that elevated both men and proved that physicality and will could match pure elegance. Battling through knees that betrayed him for two decades, he still finished with 22 Slams — a testament to the idea that pain is just information you choose to ignore.

Federer didn't just win — he made tennis look like calligraphy, gliding to 20 Grand Slam titles and 237 consecutive weeks at No.1 with a game so fluid it seemed to bend physics. The 2008 Wimbledon final against Nadal, lost in the gathering dusk, is still the sport's most cited masterpiece precisely because he lost it with such grace. He converted casual fans into obsessives and set the aesthetic template every serve-and-volley romantic still chases.

Serena arrived like a thunderclap and stayed for two decades, amassing 23 Grand Slam singles titles — more than any player in the Open Era — while rewriting who was allowed to dominate a country club sport. The 2017 Australian Open win, achieved eight weeks pregnant, is the kind of detail that turns biography into myth. She weaponized power tennis, faced racism and scrutiny no rival endured, and left the game fundamentally louder and stronger for it.

In 1988 Graf pulled off the Golden Slam — all four majors plus Olympic gold in a single calendar year — a feat so complete that nobody, man or woman, has repeated it since. Her forehand was a guillotine and her footwork balletic, carrying her to 22 Slam titles across nearly every surface with a versatility rare in any era. She spent 377 weeks at No.1, a record that stood for decades, proof that quiet dominance can be just as total as loud dominance.

Court's 24 Grand Slam singles titles remain the official record book's top line, racked up in an era of amateur tennis and split tours that make direct comparison murky but her sheer volume undeniable. She completed the calendar Grand Slam in 1970, one of only three women ever to do it, playing a serve-and-volley game ahead of her time. Her legacy is complicated by later remarks off the court, but her numbers alone force her permanently into any 'greatest ever' conversation.

Sampras made grass his personal cathedral, winning seven Wimbledon titles behind a serve so explosive it seemed to arrive before the ball left his racket. His generation-defining rivalry with Agassi gave American tennis its golden soap opera, and his 286 weeks at No.1 set a bar that lasted until Federer came along to erase it. He retired with 14 Slams and the quiet dignity of a champion who let the racket do all the talking.

Navratilova reinvented what a female athlete's body could do, bringing a weight-trained, cross-trained rigor to the court that turned her into a serve-and-volley wrecking machine and won her 18 Grand Slam singles titles. Her rivalry with Chris Evert — 80 matches, spanning over a decade — is the sport's longest-running duet, elevating both women's games to new heights. Add in a record 332 weeks at No.1 and pioneering openness about her sexuality in a hostile era, and she's as much cultural landmark as tennis legend.

Björn Borg
Borg was ice made flesh, a Swedish teenager whose topspin game and unreadable calm let him win 11 Slams — including five straight Wimbledons and six French Opens — before he walked away at 26, still near his peak. The 1980 Wimbledon final against McEnroe, that fourth-set tiebreak alone, is still shown as tennis's platonic ideal of drama. His early retirement only burnished the myth: greatness so complete it seemed to consume itself.

Agassi's career arc — punk rebel with a mullet and denim shorts collapsing to world No.141, then clawing back to No.1 in his thirties — is the sport's greatest redemption story, capped by completing the career Grand Slam on all four surfaces. His 1999 French Open win, completing that Slam after a near-decade of chaos, remains one of tennis's most improbable comebacks. Eight majors is a modest number next to the legends, but few players ever meant more to the sport's popular culture.

McEnroe was pure controversy and genius fused into one twitchy lefty, his touch and volleys as sublime as his umpire tantrums were legendary, and 'you cannot be serious' became as famous as any of his seven Grand Slam titles. His 1980s rivalry with Borg, especially that Wimbledon tiebreak classic, gave tennis its first real theater of contrasting temperaments. He redefined how much personality a champion could get away with, paving the road for every fiery star who followed.

Evert's ice-cold two-handed backhand and metronomic baseline consistency won her 18 Grand Slam singles titles and an absurd .900 career winning percentage that remains unmatched in the sport's history. Her decade-plus rivalry with Navratilova forced her to evolve from pure clay-court precision into an all-court fighter, elevating both legends in the process. She reached the semifinals or better at 52 of the 56 majors she entered — a monument to relentless, unglamorous excellence.

Laver is the answer to the sport's ultimate trivia question: the only player, man or woman, to win the calendar Grand Slam twice, once in 1962 as an amateur and again in 1969 in the Open era. His left-handed game was decades ahead of its time, and he lost prime years to the pre-Open era's ban on pros playing majors, making his 11 Slams look artificially small next to his true dominance. Wimbledon's main stadium bears his name for a reason — he's the foundational myth every subsequent 'GOAT' argument has to reckon with.

Venus broke the door down first, her booming serve and lanky athleticism announcing a new physical era in women's tennis before her sister Serena walked through it and went further. Seven Grand Slam singles titles undersell her true impact: she fought for and won equal prize money at Wimbledon in 2007, a landmark as significant as any trophy. The Williams rivalry, decades long and never less than seismic, is one of sport's great sibling sagas.

Seles's grunting, double-handed power game was rewriting the sport at terrifying speed — nine Slams by age 19 — until a stabbing by a deranged fan in 1993 stole two prime years and, arguably, the trajectory of women's tennis history. She came back and even won another major, but the 'what if' hangs over her career like a shadow no other legend on this list has to carry. Her brief reign still fundamentally changed how the game was played, ushering in the power-baseline era that defines tennis today.

Connors played with a chip on his shoulder and a two-fisted backhand that turned brawling into an art form, amassing 109 ATP singles titles — still the most ever — and eight Grand Slams across a career that stretched into his 40s. His 1991 US Open run at age 39, dragging exhausted crowds into a frenzy, is the template for every great 'one last run' story tennis has told since. Longevity and sheer competitive nastiness are his calling cards as much as any trophy count.

Lendl was the joyless robot who was actually a revolutionary, the first player to build his entire game and body around modern conditioning and heavy topspin, banking eight Grand Slam titles and 270 weeks at No.1. He lost his first four major finals before breaking through, proof of a stubbornness that later defined his legendary coaching turn with Andy Murray. He made 'boring' efficient dominance a legitimate path to greatness, whether fans liked it or not.

King's 1973 'Battle of the Sexes' win over Bobby Riggs did more for tennis's cultural footprint than most players' entire trophy case, using a tennis match to argue — and win — a case for gender equality watched by 90 million people. Her 12 Grand Slam singles titles are almost a footnote next to founding the WTA and fighting for equal prize money, work that changed the sport's entire economic structure. She's on this list less for how she won and more for what winning let her build.

Carlos Alcaraz
Alcaraz plays like he's improvising jazz at 130 miles an hour, a drop-shot-and-power hybrid that made him the youngest man to reach No.1 in the ATP rankings era and a multi-Slam champion by his early twenties. His 2022 US Open run and subsequent Wimbledon-French Open double-year stretches suggest a player already fluent across every surface, a rare trait even among legends. He's early in the story, but the ceiling being discussed is 'heir to Federer-Nadal-Djokovic,' which is as serious as praise gets.

Świątek turned Roland Garros into a fortress reminiscent of peak Nadal, her heavy topspin and relentless baseline game producing dominant clay-court runs and multiple French Open titles by her early twenties. She reached world No.1 with a game built on quiet, almost clinical intensity, a contrast to the era's louder personalities that made her dominance easy to underrate. Still building her legacy, she's already argued her way into 'best of her generation' conversations with number-one weeks and Slam counts still climbing.
