2022 Miami Open – Women's singles
Iga Świątek defeated Naomi Osaka in the final, 6–4, 6–0 to win the women's singles tennis title at the 2022 Miami Open. She became the fourth woman in history (after Steffi Graf, Kim Clijsters, and Victoria Azarenka) to complete the Sunshine Double in singles, having won Indian Wells two weeks earlier. It was Świątek's first Miami Open title, her third consecutive WTA 1000 title, and her fourth WTA 1000-level title overall. Świątek became the first woman in history to win the first three WTA 1000 titles of the year in succession, the first player since Serena Williams in 2013 to win three consecutive WTA 1000 titles, and extended her winning streak to 17 matches. She lost no sets and just 26 games en route to the title, the fewest since Martina Hingis dropped 21 games in 2000; she was the first player to win the title in Miami without dropping a set since Azarenka in 2016. Additionally, Iga Świątek won Miami Open 2022 exactly 10 years after a fellow Polish tennis player Agnieszka Radwańska (who retired in 2018), who won the tournament in 2012.

Ranked as the world No. 77, Osaka was the lowest-ranked Miami Open finalist in history, surpassing Clijsters' 2005 achievement as the then-world No. 38.
Ashleigh Barty was the two-time reigning champion, but withdrew from the tournament citing health issues. She later announced her retirement from professional tennis.
Świątek and Paula Badosa were in contention for the WTA No. 1 singles ranking at the start of the tournament after Barty requested to be removed from the WTA rankings following her retirement. Świątek became the new world No. 1 after winning her second round match, making her the 28th player and the first Pole to hold the top singles position since the computer rankings began in 1975. Świątek also became the first player born in the 21st century (male or female) to hold a world No. 1 singles ranking.
Like at Indian Wells, the international governing bodies of tennis (WTA, ATP, ITF, Australian Open, French Open, Wimbledon, US Open) allowed players from Russia and Belarus to continue to participate in tennis events on tour and at the majors, but not under the name or flag of Russia or Belarus until further notice, due to the 2022 Russian invasion of Ukraine.
