The 2006 LPGA Tour was a series of weekly golf tournaments for elite female golfers from around the world, which took place from February through December 2006.

The tournaments were sanctioned by the United States–based Ladies Professional Golf Association (LPGA).

Lorena Ochoa became the first Mexican to top the money list on the LPGA Tour, or any major international golf tour, while Annika Sörenstam held her position as the top ranked player through the whole season.

The season-ending LPGA Playoffs at The ADT was won by Paraguayan Julieta Granada.

The other seven finalists in that event featured only two Americans (Paula Creamer and Natalie Gulbis); the others were Ochoa, Webb, Koreans Il Mi Chung and Mi Hyun Kim, and Japanese Ai Miyazato.
