The 500 Festival Mini-Marathon (also known as the OneAmerica 500 Festival Mini-Marathon for sponsorship reasons^[1]) is an annual road half marathon usually held the first Saturday in May in Indianapolis, Indiana, United States.

The race began in 1977 and became an official 500 Festival event in 1979. The 13.109-mile (21.097 km) course currently starts in downtown Indianapolis, then heads west toward Speedway. It features a 2.5-mile (4.0 km) lap around the Indianapolis Motor Speedway, then returns to finish in the downtown area. From 1977 to 1992, the race was held the Friday before the Indianapolis 500. Starting in 1993, the race was moved to early May, the Saturday three weeks before the race, with rare exceptions. From 1994 to 2004, it was known as the Indianapolis Life 500 Festival Mini-Marathon.

The race regularly attracts runners and spectators from all 50 states and several countries. It includes a men's and women's running division, as well as men's and women's wheelchair entries. The Delta Dental 500 Festival 5K, a shorter version of the Mini utilizing the same start and finish lines, runs the same day. Runner's World named it among the "Most Iconic American Races" and in 2023, a USA Today readers' choice contest named it the nation's best half marathon.^[1]

In 2020, the race was cancelled for the first time in its history, due to the coronavirus pandemic.^[2] Entrants from this year's were given invitations to the 2021 race.
