Wawarsing /wəˈwɔːrsɪŋ/ is a town in Ulster County, New York, United States.

[2] The name Wawarsing was once believed to mean "a place where the streams wind" in the Lenape language, referring to the geography in the hamlet of Wawarsing; specifically, the joining of the Ver Nooy Kill and the Rondout Creek at Port Ben.

The name Wawarsing was used by the Lenape to designate the current hamlet and the fields to the north and south of it for at least six miles in both directions.

US 209 crosses the town, passing through many principal communities: Spring Glen, Laurenkill, Ellenville, Napanoch, the hamlet of Wawarsing, Soccanissing, and Kerhonkson.

The Lenape settlement "at Wawarasinke" was burned by English militiamen, led by Marten Crieger, after the Natives attacked Wiltwyck and took captives in 1663.

In 1703 the areas of Mombaccus and Wawarasink, Ulster County, were made The Town of Rochester.

During The Revolutionary War, Wawarsing, Napanoch and Pinebush (Kerhonkson area) were attacked by British raiders, who massacred many women and children and burned the farms.

The O & W Railroad Station at Port Ben was listed on the National Register of Historic Places in 2002.
