Kópavogur is a city and Iceland's second largest municipality by population.
It lies immediately south of Reykjavík and is part of the Capital Region. The name literally means seal pup bay. The town seal contains the profile of the church Kópavogskirkja with a seal pup underneath.
Kópavogur is largely made up of residential areas, but has commercial areas and much industrial activity as well. The tallest building in Iceland, the Smáratorg tower, is located in central Kópavogur.
Kópavogur is historically significant as the site of the 1662 Kópavogur meeting. This event marked the total incorporation of Iceland into Denmark-Norway when, on behalf of the Icelandic people, Bishop Brynjólfur Sveinsson and Árni Oddsson, a lawyer, signed a document confirming that the introduction of absolute monarchy by the King also applied to Iceland.
Kópavogur is also one of Iceland's most prominent sites for Icelandic urban legends about the huldufólk; it also features in this capacity in the 2010 film Sumarlandið, where the stone Grásteinn is portrayed as an elf-house in the Kópavogur municipality.
An independent township, Kópavogur is adjacent to Reykjavík.
