Sloan Lake, also known as Sloan's Lake and Sloans Lake is a body of water, park, and neighborhood in Denver, Colorado, US. The neighborhood is located on the northwest side of Denver. The lake is the central feature of Sloan's Lake Park, which is managed by the Parks and Recreation division of the City and County of Denver.

Sloan Lake is located on the western edge of Denver's city limits, adjacent to the suburbs of Lakewood, Edgewater and Wheat Ridge. The approximate boundaries are Sheridan Boulevard to the west, 17th Avenue to the south, Raleigh St. to the east, and 26th Avenue to the north. There are no tributary streams to the lake.

The true history of the creation of Sloan Lake may never be officially known, but during the settlement of the Denver area in the mid to late 19th century, the lake did not exist. A road connecting Denver and the western suburb of Golden crossed through where Sloan Lake is now. A homesteader named Thomas F. Sloan received a patent for the land from US President Andrew Johnson in December 1866. He used the land for agricultural purposes, farming and raising cattle. A commonly accepted legend states that Sloan dug a well on the land, inadvertently tapping into an underground aquifer, and that when he awoke the next morning, part of his farm land was covered in water. That flooded this part of what was known as South Golden Road, and the realigned thoroughfare now known as Colfax Avenue would become the major east-west thoroughfare in this part of the city. However, according to gold rush era stagecoach driver Bill Turner, the lake appeared sometime between when he left for Kansas in June 1861 and when he returned in early 1863. It is possible that Sloan occupied the land prior to patenting it. The lake once exceeded 200 acres (0.81 km²) and extended north and west beyond its current size, but portions were filled north of 25th Avenue and west of Sheridan Boulevard. The area surrounding the lake was once home to an amusement park and swimming facility known as Manhattan Beach. Opened to the public 27 June 1881, it was the first amusement park to be built west of the Mississippi River (it burned down in 1908 and was rebuilt as Luna Park later that year); mishaps and competition from other such attractions in the vicinity (Elitch Gardens and Lakeside Amusement Park) led to its closure in 1914. Cooper Lake, a separate body of water just southeast of Sloan Lake, fell under the jurisdiction of the federal Works Projects Administration in the 1930s, and a plan was developed which involved building channels beneath the surface of the water on both lakes. This essentially created one body of water that has commonly become known as Sloan Lake. The size of the present-day combined Sloan Lake and Cooper Lake is 177 acres (0.72 km²).
