Stansbury Park is a census-designated place (CDP) in Tooele County, Utah, United States. As of the 2020 United States Census, the population was 9,851, up from the 2010 figure of 5,145.

Stansbury Park is located in the northern end of Tooele Valley at the base of the Oquirrh Mountains. Traveling by Interstate 80, Stansbury Park is 35 minutes from downtown Salt Lake City.

Stansbury Park was proposed by the original developer (Terracor) as a planned community with a lake for sailing and canoeing, an eighteen-hole golf course, clubhouse, swimming pool, and parks. Although the original developer withdrew from the scene in the 1980s due to bankruptcy, that plan has generally been followed. The parks throughout Stansbury Park include baseball diamonds, soccer fields, basketball courts, tennis courts, play areas for children, skateboard park, and an astronomical observatory. A large park northwest of Utah State Route 138 is being developed. A natural lake (The Mill Pond) exists on the northern edge of the area; it is fed by a spring at its southeast end. The outflow water from this lake is piped around the Oquirrh Mountain Range (east of Stansbury Park) to the Kennecott Company's copper mine refinery operation (the runoff water from the lake enters a large pipe NW of the Benson Grist Mill for transport to the Kennecott operation).

The area includes several businesses, clustered in two developments at the southeast and northeast corners of the area along Utah State Route 36.

As of 2019, the community is not incorporated; thus all municipal services (except for water and sewer service) are provided by Tooele County. A proposal to incorporate was voted down in November 2016.

The 18-hole public golf course runs through the center of Stansbury Park. It contains 14 lakes. All the par 3 holes are over water and 16 of the holes have water hazards. During the winter, Stansbury Park is often the only course open in the greater Salt Lake City area. The course has a clubhouse with food service, a pro shop, putting green and driving range.

The Harmon's astronomical observatory, the Stansbury Park Observing Complex, is at the north end near the skateboard park. The observatory boasts a 40 cm (16") Ealing reflector, an 81 cm (32") reflector and a 200 mm (8") refractor along with computerized tracking and CCD imaging capabilities. The facility is owned and operated by the Salt Lake Astronomical Society. In 2017 another building was erected north of the original complex buildings, to house the world's largest amateur-built reflector telescope.

Stansbury Park has six public-education schools and one charter school. There are four public elementary schools (K through 6th grades), one junior high, and one high school. Stansbury Elementary opened in 1979, Rose Springs Elementary opened in 2005, and Old Mill opened in 2017. Stansbury Junior High (7-8 grade) opened in 2025. Stansbury High School (9th through 12th), just southwest of Rose Springs Elementary School, opened in August 2009. Bonneville Academy, on the west edge of Stansbury Park, is a K-8 Charter school with a focus on STEM education.
