Vågan was established as a municipality on 1 January 1838 (see formannskapsdistrikt law). In 1856, the northwestern part of Vågan Municipality (population: 987) was separated to form the new Gimsøy Municipality. On 1 July 1918, the town of Svolvær (population: 2,429) was separated to form its own municipality. This left Vågan with 3,399 residents. During the 1960s, there were many municipal mergers across Norway due to the work of the Schei Committee. On 1 January 1964, the municipalities of Gimsøy (population: 1,551), Svolvær (population: 3,952), and Vågan (population: 4,820) were merged to form the new, larger municipality of Vågan.
The municipality (originally the parish) is named after the old Vågan farm (Old Norse: Vágar), since the first Vågan Church was built there. The name is the plural form of vág which means "bay". The island of Austvågøya (Old Norse: Vágøy) was named after this important site (which later led the neighboring island to be named Vestvågøya). The name was historically spelled Vaagan.
The coat of arms was granted on 30 March 1973. The official blazon is "Azure, a cod embowed argent" (På blå bunn en vertikalstillet fremadbøyd sølv torsk). This means the arms have a blue field (background) and the charge is a cod. The cod has a tincture of argent which means it is commonly colored white, but if it is made out of metal, then silver is used.
