Saint-Ursanne is an old town and a former municipality of the district of Porrentruy in the canton of Jura, Switzerland which has preserved much of its medieval character.

The river Doubs makes a loop near Saint-Ursanne before flowing into France. Since 2009 Saint-Ursanne has been a part of the new municipality Clos du Doubs. An active railway station is located above the town, to the east. The town is famous for the medieval festival which it organizes each summer, and for the annual St-Ursanne - Les Rangiers International Hill Climb in August. Its name refers to Saint Ursicinus, a seventh-century monk who built a monastery here. This town received an award as being one of the "best tourism villages" worldwide by UNWTO.
