The 2011 LPGA Championship was the 57th LPGA Championship, held June 23–26 at Locust Hill Country Club in Pittsford, New York, a suburb southeast of Rochester. Known for sponsorship reasons as the Wegmans LPGA Championship, it was the second of four major championships on the LPGA Tour during the 2011 season. This was the second of four consecutive years the LPGA Championship was played at Locust Hill.

The champion was Yani Tseng, age 22, with a 269 (−19) to win by ten strokes over Morgan Pressel. It was Tseng's second LPGA Championship victory (2008) and fourth major championship. It was her third victory of 2011 and eighth career win on the LPGA Tour. It was the second consecutive year with a double-digit victory margin. Defending champion Cristie Kerr tied for third, eleven strokes back; she won by twelve strokes in 2010.
