Catskill is a town in the southeastern section of Greene County, New York, United States. The population was 11,298 at the 2020 census, the largest town in the county. The western part of the town is in the Catskill Park. The town contains a village, also called Catskill. The village of Catskill has a well-defined Main Street. There is a public boat launch on the Hudson River called Dutchman's Landing.

The first settler was Derrick Teunis van Vechten, who built a house here in 1680. The town was established on March 7, 1788, as part of Albany County. When Greene County was formed on March 25, 1800, Catskill became part of the new county. The town was increased by an addition from the town of Woodstock in 1800, but was later decreased upon the formation of the towns of Cairo (1803) and Athens (1815). Catskill is the location of the story "Rip Van Winkle" by Washington Irving.

On July 23, 2003, an F2 tornado ripped across the town. The worst of the damage occurred at the Kiskatom flats. The tornado crossed over New York Route 32 and went past the Friar Tuck Inn, causing two mobile homes to flip over.
