Sørreisa (Northern Sami: Ráisavuona suohkan) is a municipality in Troms county, Norway.

[6] On 1 January 2020, the municipality became part of the newly formed Troms og Finnmark county.

The river name is derived from the verb rísa which means "to raise" (referring to flooding).

The official blazon is "Gules, three six-pointed mullets Or" (Norwegian: I rødt 3 seksoddete gull stjerner, to over en).

Each star has a tincture of Or which means it is commonly colored yellow, but if it is made out of metal, then gold is used.

The seal belonged to the local politician Jacob Hansen Kinapel who was a policeman in Sørreisa from 1715 to 1748.

Sørreisa is located on the western coast of Norway, along the Reisafjorden, just east of the large island of Senja.

The municipal council (Kommunestyre) of Sørreisa is made up of 19 representatives that are elected to four year terms.
