Oudeschans (Dutch pronunciation: [ˈʌudəˌsxɑns]) is a small village with a population of around 100 in the municipality of Westerwolde in the province of Groningen in the Netherlands.

The 16th-century fortification is now a state protected village area with several national heritage sites, among which include a 17th-century garrison church, and the Vestingmuseum Oudeschans.
