2006 WGC-Accenture Match Play Championship

The 2006 WGC-Accenture Match Play Championship was a golf tournament that was played from February 22–26, 2006 at La Costa Resort and Spa in Carlsbad, California. It was the eighth WGC-Accenture Match Play Championship and the first of four World Golf Championships events held in 2006. It was the final time the event would be hosted at La Costa.

Geoff Ogilvy, the 12th seed, won his first World Golf Championships event by defeating Davis Love III 3 and 2 in the 36 hole final. He set a record by playing a total of 129 holes during the tournament, the most by anyone in the eight-year history of the event, which included four consecutive overtime matches at the start of the week. The total prize fund for the championship was $7.5 million, of which Ogilvy's share was $1.3 million.

Tiger Woods set the record for largest victory margin with a 9 and 8 win over Stephen Ames in the first round. Some interpreted Woods' performance as payback for Ames' comments earlier in the week in which he told the Associated Press, "anything can happen, especially where he's hitting it."
