The 2021 Masters Tournament was the 85th edition of the Masters Tournament and the first of the men's four major golf championships held in 2021. It was held from April 8–11, 2021, at the Augusta National Golf Club in Augusta, Georgia.

After the 2020 tournament had been postponed to November because of the COVID-19 pandemic and held behind closed doors, the 2021 edition returned to its traditional April dates and admitted spectators, although in reduced numbers and with social distancing measures in place. For the second year in succession, the traditional Par-3 contest was canceled due to these restrictions.

Hideki Matsuyama became the first Japanese male golfer to win a major championship, and the first Asian-born golfer to win the Masters, finishing with a 72-hole score of 278 (−10), one shot ahead of Will Zalatoris.

Participation in the Masters Tournament is by invitation only, and the tournament has the smallest field of the major championships. There were a number of criteria by which invites were awarded, including all past winners, recent major champions, leading finishers in the previous years' majors, leading players on the PGA Tour in the previous season, winners of full-point tournaments on the PGA Tour during the previous 12 months, leading players in the Official World Golf Ranking and some leading amateurs.
