Lake Pleasant Regional Park is a large outdoors recreation area straddling the Maricopa and Yavapai county border northwest of Phoenix, Arizona.

The park is located within the municipal boundaries of Peoria, Arizona, and serves as a major recreation hub for the northwest Phoenix metropolitan area.

Lake Pleasant is used as a major water sports recreation center for the Phoenix metro area, as well as serving as an important storage reservoir for the rapidly growing region.

The rapidly growing city of Peoria annexed the park and surrounding lands with an eye on future development, though the 2007–2008 economic downturn brought a temporary halt to its plans.

[4] Economy aside, the increasing popularity of the area is evidenced by rapidly growing subdivisions to the south, such as Vistancia, and skyrocketing real estate values, the city has zoned much of the land in the immediate vicinity for future use of both high-end waterfront residential neighborhoods and commercial opportunities off of Lake Pleasant Parkway and the Carefree Highway.
