Martensville is a city located in Saskatchewan, Canada, just 8 kilometres (5.0 mi) north of Saskatoon, 10 kilometres (6.2 mi) west of the city of Warman and 14 kilometres (8.7 mi) southwest of Clarkboro Ferry which crosses the South Saskatchewan River. It is a bedroom community of Saskatoon. It is surrounded by the Rural Municipality of Corman Park No. 344. The community is served by the Saskatoon/Richter Field Aerodrome located immediately west of the city across Highway 12, as well as by Saskatoon's John G. Diefenbaker International Airport, only a few miles to the south.

In 1939, Isaac Martens (1887–1987) and his son Dave Martens (1908-1984) purchased land north of Saskatoon. They then sold three small parcels of land to people who wanted to move out of Saskatoon and, as a result, the community of Martensville was created. Many Mennonites who worked in Saskatoon chose to live there to retain connections to the large Mennonite community of the Hague-Osler area.

Martensville was later incorporated as a village in 1966 and as a town three years later in 1969. Sewer and water was established in 1976 with the town experiencing accelerated growth. In 1992, the town was rocked by an alleged satanic sex scandal which made national headlines, also known as the Martensville satanic sex scandal. In 2009, Martensville was incorporated as a city.

It belongs to the continental climate region of Canada which typifies warm summers according to the Köppen climate classification. The geology of the area are sandy plains which resulted from shorelines of glacial lakes and depositions from glacial lakes as the Laurentide Ice Sheet left the area. There are no large lakes in this area due to the sandy soils which drained away melting glacial waters. The lakes in this area are remnants of the South Saskatchewan river channels.
