Arnold Palmer Invitational presented by MasterCard: Birdied the 72nd hole to beat Sean O'Hair by one stroke and claim his sixth Arnold Palmer Invitational presented by MasterCard. Sank a 15-foot birdie putt on the final green, duplicating his last-putt heroics from two previous years (2001, 15-foot birdie putt to beat Phil Mickelson; 2008, 24-foot birdie putt to beat Bart Bryant). Matched his largest comeback after 54 holes (five strokes) with his victory. He also came back from five strokes behind after 54 holes to win the 2000 AT&T Pebble Beach National Pro-Am (Mark Brooks and Matt Gogel). Out of 66 career wins, it was his 19th coming from behind. Became the first player to win six Arnold Palmer Invitational titles. The only other players with multiple victories at the event are Tom Kite (1982 and 1989) and Loren Roberts (1994-95).
BMW Championship: Captured his sixth title of the season and took the lead in the FedExCup standings with an eight-stroke victory over Jim Furyk and Marc Leishman at the BMW Championship. Shot a third-round, course-record 62 at Cog Hill to take a seven-stroke lead entering the final round and finished at 19-under 265 to win for the fifth time at Cog Hill. It was his 10th career PGA TOUR victory by at least eight shots. It was also his 71st career victory, two short of Jack Nicklaus for second on the PGA TOUR's career list. Also tied Sam Snead with his sixth season of at least six victories.
Farmers Insurance Open: At the beginning of the year, committed to the Farmers Insurance Open, The Honda Classic and the Omega Dubai Desert Classic on the European Tour.

Missed the 36-hole cut after a second-round 72 for a 4-over total.
World Golf Championships-Accenture Match Play Championship: Defeated Stewart Cink 8 and 7 in the 36-hole championship match to capture the World Golf Championships-Accenture Match Play Championship for the third time.

The Open Championship: Jumped to No. 2 in the Official World Golf Ranking, with a T3 finish at The Open Championship, his best performance in a major championship since finishing runner-up at the 2009 PGA Championship. Final-round 73 included a triple bogey on the par-4 sixth hole, his first triple in a major championship since the first hole at the 2003 Open Championship (Royal St. George's).

Woods played in his first 2020 PGA Tour event at the Zozo Championship in October 2019, which was the first-ever PGA Tour event played in Japan. Woods, who played a highly publicized skins game earlier in the week at the same course as the Championship, held at least a share of the lead after every round of the rain-delayed tournament, giving him a three stroke victory over Hideki Matsuyama. The win was Woods's 82nd on Tour, tying him with Sam Snead for the most victories all time on the PGA Tour.
