The 2020 ANA Inspiration was the 49th ANA Inspiration LPGA golf tournament, held on the Dinah Shore Tournament Course at Mission Hills Country Club in Rancho Mirage, California. Originally scheduled for April 2–5, the tournament was postponed to September 10–13, due to the COVID-19 pandemic. This was its 38th year as an LPGA major championship, and it was the second major of 2020 following the AIG Women's Open, held in August.

The championship was held in a bubble and behind closed doors, although residents of the Mission Hills gated community were able to watch from within the boundaries of their own homes. A large blue colored structure, dubbed the "Big Blue Wall", was erected behind the 18th green, where a grandstand would normally have been, in order to promote the championships main sponsor. This attracted much criticism since it served as a backstop, preventing approach shots from going into the water behind the green.

Due to expected conditions in the California desert in September, with forecast temperatures in excess of 105 °F (41 °C), the LPGA allowed caddies to ride in carts for the duration of the tournament. Players could also ride in carts during practice rounds, but were still required to walk during the tournament.

Mirim Lee won her first major championship with a birdie at the first extra hole of a playoff with Brooke Henderson and Nelly Korda. The three had tied at 273 (15-under-par) after 72 holes. The big blue wall played its part, as both Lee and Henderson used the backstop on the final hole of regulation play to make eagle and birdie respectively to tie Korda, who could only make par.

Players were eligible to compete in the ANA Inspiration by means of various qualification criteria. Those who received exemptions included past champions, recent LPGA major winners, leading players from the LPGA Tour and the U.S. Women's Amateur champion. On September 4, a field of 105 players was confirmed.

Seven past champions were in the field; Pernilla Lindberg, Lydia Ko, Brittany Lincicome, Lexi Thompson, Stacy Lewis, Morgan Pressel and seven-time major winner Inbee Park. Other leading contenders included 2017 Women's PGA Champion and world number two Danielle Kang, world number three Nelly Korda, and two-time major winner and world number four Park Sung-hyun. Among the six amateurs in the field were U.S. Women's Amateur champions Rose Zhang (2020) and Gabriela Ruffels (2019).

Several past champions did not compete; they included defending champion and world number one Ko Jin-young and 2017 winner Ryu So-yeon. Also missing were many other leading South Korean players, including Kim Hyo-joo and Lee Jeong-eun, numbers 10 and 11 respectively in the world rankings. 2020 Women's British Open champion Sophia Popov was also not in the field as her exemption for winning the first major of 2020 was not active until 2021.

Two days prior to the tournament starting, England's world number 28 Charley Hull was forced to withdraw from the field after testing positive for COVID-19. The LPGA reported that no other players had returned a positive test.

Overnight leaders Brooke Henderson and Nelly Korda shared and alternated the lead for much of the final round, with neither able to stretch their lead beyond one stroke until a double-bogey on the 13th hole by Henderson was followed by a birdie on the 14th hole by Korda, which moved her to 15 under par. Mirim Lee closed to within one stroke of Korda with a chip-in for birdie on the 16th hole, her second hole-out of the day after chipping in on the 6th hole. Henderson also made a birdie on the 16th to move back to 14 under par as Lee dropped back to 13 under par with a bogey on the 17th.

On the par-5 closing hole, Lee hit her second shot over the green and, after taking a free drop from against the blue wall, proceeded to chip-in for an eagle, her third hole-out of the day, to tie Korda at 15 under par. Playing behind Lee, Korda drove into the rough and had to lay-up short of the water guarding the front of the final green. Henderson was able to go for the green and, like Lee, went over the back with her ball finishing inside the blue wall. Korda could only make par after missing the green with her approach, and Henderson, having taken a free drop, was able to get up-and-down for birdie to tie Korda and Lee and force a three-way playoff for the title.

Rose Zhang, the 2020 U.S. Women's Amateur champion, finish tied for 11th with an 8-under-par 280, taking low-amateur honors. Her 72-hole score of 280 was the lowest amateur score in the tournament's history. Her finish allowed her to reach number 1 in the World Amateur Golf Ranking.
