The Grant Thornton Invitational is an annual golf tournament for two-player mixed teams, consisting of PGA Tour and LPGA Tour players.

It is held at the Tiburón Golf Club in the Naples, Florida.

It was first played in 2023 and replaced the QBE Shootout on the PGA Tour schedule.

It debuted as the first mixed-team event since the end of the JCPenney Classic in 1999.

The inaugural tournament was won by New Zealander Lydia Ko and Australian Jason Day, who bested a Canadian team by a single stroke.
