Souris (2006 population: 1,232) is a Canadian port town in northeastern Kings County, Prince Edward Island. Located in an area famous for its beaches, the town is sometimes called the "gateway to Basin Head".
Souris was founded by Acadians in 1727 as a fishing settlement. These early settlers experienced several plagues of field mice in the surrounding area during the 1720s-1760s and the name for the town is derived from the French word for mouse.
The economy of the area is dominated by the seasonal industries of fishing, agriculture and tourism.
Since the 1960s, Souris has hosted an interprovincial ferry terminal for the service to Quebec's Magdalen Islands. The MV Madeleine is operated by the Coopérative de transport maritime et aérien (CTMA).
