The Indiana Oaks is a Grade III American Thoroughbred horse race for three-year-old fillies run over a distance of 1+1⁄16 miles on the dirt held annually in July at Horseshoe Indianapolis in Shelbyville, Indiana.

The Indiana Oaks was inaugurated on 16 September 1995 at Hoosier Park and run over a distance of 1 mile. The event was won by the short odds-on Niner's Home who withstood the fast closing Alltheway Bertie to win by a neck in a time 1:37 flat on a fast track.^[1]

The event was held over a mile in 1996 before being extended to the current distance of 1+1⁄16 miles in 1997.^[2]
