Sorenstam will make her first appearance at the event since 1995 when she tied for seventh.
'We are elated that Annika has decided to play Corning,' said LPGA Corning Classic president Jack Benjamin. 'This is sensational news for our sponsors, spectators and charities. Her appearance here could add an additional 10,000 fans for this year's tournament.'
Sorenstam has won twice so far in 2004 giving her 50 career victories on the LPGA Tour.
The LPGA Corning Classic will be contested from May 27-30 at Corning Country Club. Juli Inkster won the event in 2003.
