Canaseraga Creek is a stream that flows through Livingston, Steuben, and Allegany Counties in western and central New York.

[5] Canaseraga Creek rises in the town of Nunda, and initially flows south.

It is primarily composed of agricultural land (46.8%) and forests (44.4%), with 5.7% of the watershed developed for residential and industrial uses.

[2] The main stem of Canaseraga Creek is annually stocked with brown trout by the New York State Department of Environmental Conservation; in 2015, the creek was stocked with 5,670 trout at locations in Allegany and Steuben counties.

An eight-mile (13 km) stretch of the creek upstream of Dansville contains class IV and V rapids, although water levels are frequently too low for rafting outside of spring flooding events.
