Tromøy (historic: Tromø) is a former municipality of Norway in Aust-Agder county. The 30-square-kilometre (12 sq mi) municipality existed from 1878 until its dissolution in 1992. The municipal area is now part of the municipality of Arendal. The administrative centre was the village of Brekka, where the historic Tromøy Church is. The municipality encompassed all of the island of Tromøya as well as many smaller surrounding islands such as Merdø, Gjesøya, Skilsøy, and Tromlingene.
The municipality had two churches: the centuries-old Tromøy Church and the relatively new Færvik Church. Some of the main villages in Tromøy were Færvik, Brekka, Brattekleiv, Sandnes, Revesand, and Pusnes. The municipality was connected to the mainland by the Tromøy Bridge, the only road connection to Tromøya. The other islands of Tromøy were only accessible by boat.
The municipality of Tromøy was established on 1 May 1878 when the municipality of Østre Moland was divided into three municipalities: Tromøy (population: 2,320), Barbu (population: 4,874), and Østre Moland (population: 2,524). On 1 January 1992 there was a major municipal merger where the following municipalities were merged into the municipality of Arendal: Tromøy (population: 4,711), Moland (population: 8,148), Øyestad (population: 8,679), Hisøy (population: 4,026), and the town of Arendal (population: 12,478).
The municipality (originally the parish) was named after its island Tromøya. Historically it was spelled Tromø, but more recently it has been spelled Tromøy. The name comes from the Old Norse Þruma, which means "rim", "edge", or "border". The suffix -ø or øy means "island".
The coat of arms is from modern times; it was granted on 23 August 1985. The blue and white arms represent the sea and the coastline near the village of Brekka, which is characterised by large rounded boulders protruding out into the sea. This landscape dates back to the Ice Age and was used to model the division line in the coat of arms.
