Giske is an island municipality in Møre og Romsdal county, Norway.

The initial population of the new municipality was 1,708 and it included the islands of Valderøya, Godøya, and Giske.

The name comes from the word gizki which means "tablecloth" or "rag" (maybe because the island is small and flat).

The official blazon is "Azure, a lion rampant guardant Or" (Norwegian: På blå grunn ei opprett leopardiset gull løve).

This means the arms have a blue field (background) and the charge is a lion that is rampant (i.e. in walking position) and guardant (i.e. facing the viewer).

The lion 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 municipal council (Kommunestyre) of Giske is made up of 23 representatives that are elected to four year terms.

Interestingly, in the 2007 municipal elections, Giske recorded the highest vote for the Christian Democratic Party in all of Norway at 43.2 percent.

Giske is the site of Mjelthaugen, an ancient burial place dating from the Bronze Age.

Giske is also the place where, according to Snorre Sturlason, Harald Fairhair had his hair cut after uniting Norway.
