The 2021 Iga Świątek tennis season officially began on 1 February 2021 as the start of the 2021 WTA Tour. Iga Świątek entered the season as world number 17 in singles. The season saw the Polish player won two WTA singles titles and reached a career-high world number 4.
Season summary Early hard court season Świątek advanced to the quarterfinals at the Gippsland Trophy to start her season, where she was defeated by Ekaterina Alexandrova in straight sets. At the Australian Open, her performance was marred by a significant number of unforced errors, leading to her fourth-round loss to Simona Halep in three sets. In the Adelaide International, Świątek clinched her first title of the year without losing a set. This achievement allowed her to ascend into the top 15 in the singles rankings. However, during the Miami Open, Świątek was ousted in the third round by Ana Konjuh in a three-set encounter.
Clay season Świątek's next tournament was the Madrid Open, where she made her tournament debut. She reached the third round and lost to the world no. 1 Ashleigh Barty in straight sets. She then won her second title of the year at the Italian Open, defeating former champion Karolína Plíšková in just 46 minutes by sending a double-bagel. The title also saw her move into the top 10 on 17 May 2021, as world no. 9.
Świątek failed to defend her French Open singles title, but she did reach the quarterfinals, where she lost to Maria Sakkari in straight sets. However, she reached the final in doubles with her partner Bethanie Mattek-Sands, but they lost to Czech Republican pair of Barbora Krejčíková and Kateřina Siniaková in straight sets.
Grass season Świątek participated in Eastbourne as the start of her grass season, but she was upset by Daria Kasatkina in the second round despite winning the first set. At Wimbledon, she reached fourth round, where she lost to Ons Jabeur in three sets.
US Open series Following a second-round loss against Paula Badosa at the Summer Olympics, Świątek then had an early exit in Cincinnati, where she once again lost to Ons Jabeur. Świątek then entered the US Open and reached the fourth round, marking her the only player to have reached the second week of all four Grand Slam championships in the 2021 season.
Closing tournaments Świątek entered the Ostrava Open as the top seed. She reached semifinals before losing to Maria Sakkari in straight sets. She subsequently lost in the fourth round match against Jeļena Ostapenko in Indian Wells. Nevertheless, Świątek still qualified WTA Finals for the first time in her career.
Świątek failed to advance into the semifinals at the WTA Finals, respectively losing to Maria Sakkari in two sets and Aryna Sabalenka in three sets. However, she did manage to wrap up her 2021 campaign with a victory over Paula Badosa. She eventually finished the season as world no. 9.
