Tuolumne River Regional Park, Regional park along Tuolumne River in Stanislaus County, United States.

Tuolumne River Regional Park is a 500-acre public park under development along a seven-mile stretch of the Tuolumne River between Ceres and Modesto in Stanislaus County. Its completed plan sets aside 150 acres of developed parkland in four parks and 350 acres for riparian habitat restoration, linked by over five miles of pedestrian and biking trails.

Planning for the park began in the 1920s and led to the construction of Dennett Dam and Lake Modesto in 1933. These structures were destroyed by flooding in 1940, which shaped how the park developed afterward.

The name comes from the Tuolumne River, which the Tuolumne River Coalition works to protect along its lower 52 miles from LaGrange Dam to the San Joaquin confluence. Mancini Park, on the Ceres side, was developed on land donated by conductor Frank Mancini. Legion Park, established in the 1970s, is planned as the park's educational centre, with a restored wildflower meadow and a kayaking beach.

The park is under development, with completed sections including Mancini Park, Beard Brook Park, Legion Park and Bellenita Park. A pedestrian and bicycle bridge is planned to link Mancini Park to the trail system. The future RiverWalk Trail will run seven miles along the river.

The park's management operates through a Joint Powers Authority involving three separate local governments: Stanislaus County, the city of Ceres, and the city of Modesto. This cooperation model demonstrates an unusual approach to how different communities jointly care for and operate the park.
