Horsetooth Reservoir (often known locally as Horsetooth) is a large reservoir in southern Larimer County, Colorado, just west of the city of Fort Collins, Colorado. The reservoir sits in the foothills above the town on the western side of the Dakota Hogback, which contains the reservoir along its eastern side. The reservoir runs north-south for approximately 6.5 miles (10 km) and is approximately one-half mile (1 km) wide. It was constructed in 1949 by the Bureau of Reclamation as part of its federal Colorado-Big Thompson Project or "C-BT". Water distribution is currently managed by Reclamation and operated by the Northern Colorado Water Conservancy District. Horsetooth and Carter Lake serve as the two principal reservoirs for water diverted eastward under the continental divide via the C-BT.

The reservoir is a supplementary source of municipal water for Fort Collins, Greeley and other communities in the region, as well as for irrigation in the lower South Platte River basin. The reservoir takes its name from Horsetooth Mountain, a summit in the foothills west of the southern end of the reservoir.
