The area of present-day Mamurogawa was part of ancient Dewa Province and the location of Sakenobe Castle in the Sengoku period. After the start of the Meiji period, the area became part of Mogami District, Yamagata Prefecture. The village of Mamurogawa was established on April 1, 1889 with the establishment of the modern municipalities system. During World War II, an airbase for training pilots was established by the Imperial Japanese Army. The site is now a park, and part of the grounds of the local high school. Mamurogawa was elevated to town status on April 1, 1950. On August 1, 1954, it absorbed the neighboring villages of Araki and Nozoki.
The economy of Mamurogawa is based on agriculture and forestry.
