Mārupe Municipality is a municipality in Latvia, mostly in Vidzeme region, immediately to the southwest of the capital city of Riga. The municipality was formed in 2009 by reorganization of Mārupe Parish. The administrative centre is the town of Mārupe. The municipality borders the city of Riga to its east and north-east, the city of Jurmala to its north, and the municipalities of Tukums to its west, Jelgava to its southwest, Olaine to its south and southeast.

Vidzeme is one of the Historical Latvian Lands. The capital of Latvia, Riga, is situated in the southwestern part of the region. Literally meaning "the Middle Land", it is situated in north-central Latvia north of the Daugava River. Sometimes in German, it was also known as Livland, the German form from Latin Livonia, though it comprises only a small part of Medieval Livonia and about half of Swedish Livonia. Most of the region's inhabitants are Latvians (85%), thus Vidzeme is the most ethnically Latvian region in the country.
