The Milwaukee Mile is a 1.015 mi (1.633 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 1.800 mi (2.897 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.

The track was a one mile (1.6 km) private horse racing track by 1876. In 1891, the site was purchased by the Agricultural Society of the State of Wisconsin to create a permanent site for the Wisconsin State Fair (which it still is).

The first motorsports event was held on September 11, 1903. William Jones of Chicago won a five lap speed contest, and set the first track record with a 72-second, 50 mph (80 km/h) lap. There were 24-hour endurance races in 1907 and 1908. Louis Disbrow won the first 100-mile (160 km) event in 1915, averaging 62.5 mph (100.6 km/h).

With the release of the 2023 NASCAR schedule it was officially announced that NASCAR was returning to the historic Milwaukee Mile Speedway at Wisconsin State Fair Park. The NASCAR CRAFTSMAN Truck Series will make its stop at the Milwaukee Mile on Sunday, August 27, 2023.
