Regina Beach is a town in south central Saskatchewan, located on Highway 54, close to where Highway 11 intersects with the Qu'Appelle Valley. As Regina Beach rests on shores of the south end of Last Mountain Lake, it becomes an active lakeside resort town in summer. To the east is Buena Vista, their boundary marked by 16 Street. About 5.6 kilometres south of town in the RM of Lumsden No. 189, is the Regina Beach Airport.
