The municipality is one of very few in Sweden which has not been amalgamated and thus still has the same area as the unit formed out of a parish (socken) by the first local government acts of 1862. In the period 1915–1959 there were a number of municipalsamhällen (a sort of boroughs within a rural municipality handling matters of urban character) in the municipality.
The municipality consists of ten year-round inhabited islands. They are considered to stretch from a renowned lighthouse called Vinga fyr up to the coastal town of Marstrand in the municipality of Kungälv. The ten islands are named:
N.B. that "ö" means "island" in Swedish, hence all names end with "ö". E.g. Björkö means "Birch Island".
Of these, Hönö is the largest with some 4,800 inhabitants, and Öckerö is also fairly large with 3,100. However, all ten are inhabited by people all year around. Most islands have bridge connection between each other. However, there is no road connection to the mainland, just car ferries from western Gothenburg. The ferry connections are good with a dense schedule. A local referendum in 2003 in Öckerö Municipality rejected the plans for a future bridge to the mainland.
During the Viking Age the islands of Öckerö belonged to the Norwegian kings, and the part of the coast was known as Älvsyssel. In the 13th century the King Håkon Håkonsson of Norway built himself a house on Öckerö, because he was often around there with his navy.
In 1658 or thereabout, the area became Swedish together with Bohuslän.
In the 1950s the coat of arms were designed. As the main industry has always been fishing, a boat and herring became symbols. The ten herrings correspond to the ten islands.
Ömål, also called öbo, is a Swedish Götamål dialect spoken on the islands of the Öckerö municipality. It has some features of the Gothenburg Swedish dialect (Göteborgska), but also features from English.
