Winterswijk (Dutch pronunciation: [ˌʋɪntərsˈʋɛik] ⓘ; also known as Winterswiek or Wenters) is a municipality and a town in the eastern Netherlands.

It was also known as Winethereswick, Winriswic or Wenterswic; the Low Saxon wich or wic means the living place of a certain person.

Founded around 1000 AD it remained an isolated farming community until 1830 when the road from Borken to Zutphen via Winterswijk and Groenlo was built.

After 1870 the town became a centre for textiles, such as spinning and weaving and indeed the Tricot factory employed a large proportion of the local population in its heyday.

In 1878 the railway line to Zutphen was built primarily for the textile industry, which was set up by Jan Willink.
