The Milwaukee Mile is a one-mile-long (1.6 km) oval race track in the central United States, located on the grounds of the Wisconsin State Fair Park in West Allis, Wisconsin, a suburb west of Milwaukee. Its grandstand and bleachers seats approximately 37,000 spectators. Paved 68 years ago in 1954, it was originally a dirt track. In addition to the oval, there is a 1.8 mile (2.8 km) road circuit located on the infield.

As the oldest operating motor speedway in the world, the Milwaukee Mile has hosted at least one auto race every year from 1903 to 2015 (except during U.S. involvement in World War II). The track has held events sanctioned by major bodies, such as the AAA, USAC, NASCAR, CART/Champ Car World Series, and the IndyCar Series. There have also been many races in regional series such as ARTGO.

Famous racers who have competed at the track include: Barney Oldfield, Ralph DePalma, Walt Faulkner, Parnelli Jones, A. J. Foyt, Al Unser, Bobby Unser, Mario Andretti, Bobby Rahal, Jim Clark, Darrell Waltrip, Alan Kulwicki, Emerson Fittipaldi, Bobby Allison, Davey Allison, Nigel Mansell, Rick Mears, Michael Andretti, Alex Zanardi, Harry Gant, Rusty Wallace, Walker Evans, Dario Franchitti and Bernie Eccelstone as well as current racing stars Danica Patrick, Dale Earnhardt Jr., Jeff Gordon, Tony Kanaan, Scott Dixon, Hélio Castroneves, A. J. Foyt IV, Simona de Silvestro, Colin Braun, James Davison, Paul Newman, Jay Drake, Nick Bussell, Sage Karam and many others.

On December 16, 2009, Wisconsin State Fair Park officials confirmed that the Milwaukee Mile would not host any NASCAR or IndyCar races in 2010. NASCAR confirmed that their June Nationwide Series date would remain in Wisconsin for 2010, as they announced they would hold a race at Road America for the first time since the Grand National Series raced there in 1956. NASCAR also announced on January 20, 2010, that the Milwaukee date for the truck series would be moved to August. The track hosted two ASA Late Model Series races in 2010.IndyCar returned to the track in 2011, but the Mile was left off of the preliminary 2012 schedule after a poorly attended 2011 event that resulted in part from an inexperienced promoter. In February 2012, it was announced that IndyCar would return to the Mile on the weekend of June 15–16. The event was promoted by Andretti Sports Marketing, owned by former Indy driver Michael Andretti, and was billed as the Milwaukee IndyFest. The event included open-wheel racing featuring the IndyCar Series and the Firestone Indy Lights, as well as a driver question period and autograph sessions, music and other attractions. The series again left after the 2015 season, and the track hosted no major professional races until ARCA returned in 2021.
