Mutsu was founded on September 1, 1959 through the merger of the former towns of Ōminato and Tanabu. Tanabu had been the location of a daikansho under the Morioka Domain in the Edo period, and was a resettlement and colonization zone for dispossessed ex-samurai of the defeated Aizu Domain after the Boshin War. The village of Ōminato was established with the creation of the modern municipalities system on 1 April 1889, and was raised to town status on November 10, 1928. Ōminato was a port town, and home to the Ōminato Guard District, a major base for the Imperial Japanese Navy until the end of World War II. The town and its military base were bombed repeatedly from the middle of July to middle of August 1945 during World War II. The base facilities were used by the United States Navy during the occupation of Japan, and (on a reduced scale) by the Japan Maritime Self Defence Force to date.

Ōminato merged with the adjacent town of Tanabe to form the city Ōminato-Tanabu (coupling of the names of two antecedent towns) on September 1, 1959; its name was changed to Mutsu in 1960. At the time, it was the only city with a hiragana name (むつ), which was adopted to avoid confusion with the original kanji word Mutsu (陸奥) which indicates the old province that covered most of the modern Tōhoku region.

On March 14, 2005, the towns of Kawauchi and Ōhata, and the village of Wakinosawa (all from Shimokita District) were merged into Mutsu.

Mutsu has a mayor-council form of government with a directly elected mayor and a unicameral city legislature of 26 members. Mutsu, together with Shimokita District, contributes three members to the Aomori Prefectural Assembly. In terms of national politics, the city is part of Aomori 1st district of the lower house of the Diet of Japan.

The economy of Mutsu is heavily dependent on agriculture, forestry and fishing, especially scallop aquaculture in Mutsu Bay. The city is also the location for various facilities of the Japan Atomic Energy Agency, and was the home port for the nuclear powered research vessel Mutsu, until its decommissioning in 1997.

Mutsu has 12 public elementary schools and nine middle schools operated by the city government, and four public high schools operated by the Aomori Prefectural Board of Education. The Aomori Akenohoshi Junior College has a campus in Mutsu. The prefecture also operates two special education schools for the handicapped.
