The Town of Ogema is located in south central Saskatchewan, approximately 115 kilometres south of Saskatchewan's capital city, Regina. Ogema is located midway between Weyburn and Assiniboia on Highway 13, which runs through the southern part of the province. The Red Coat Road and Rail short-line railway runs through Ogema and brings producer cars to the Ogema Elevator. The rail line is also home to Southern Prairie Railway, Saskatchewan's first full-sized tourist railway.
The Rural Municipality of Key West, which includes the town of Ogema, is located centrally in the southern part of Saskatchewan on the Missouri Coteau. The coteau is characteristically composed of rolling hills and shallow sloughs known as knob and kettle topography.
