Sea-Doo is a Canadian brand of personal watercraft (PWC) and boats manufactured by Bombardier Recreational Products (BRP). All Sea-Doo models are driven by an impeller-driven waterjet. All Sea-Doo PWC models are produced at BRP's plants in Querétaro and Juárez, Mexico. Its Rotax engines are produced at BRP's plant in Gunskirchen, Austria. In 2016, Sea-Doo had a 45.8% share of the PWC market.

A personal watercraft (PWC), also called jet ski, sea-doo, or water scooter, is a primarily recreational watercraft that is designed to hold only a small number of occupants, who sit or stand on top of the craft, not within the craft as in a boat.
