Frederiksberg (Danish pronunciation: [fʁeðʁeksˈpɛɐ̯ˀ, fʁæðʁæksˈpɛɐ̯ˀ]) is a part of the Capital Region of Denmark. It is an independent municipality, Frederiksberg Municipality, separate from Copenhagen Municipality, but both are a part of the region of Copenhagen. It occupies an area of less than 9 km and had a population of 103,192 in 2015. It is the most densely populated municipality in Denmark.
Frederiksberg is an enclave surrounded by Copenhagen Municipality. Some sources ambiguously refer to Frederiksberg as a quarter or neighbourhood of Copenhagen, being one of the four municipalities in Copenhagen zone (the other three being Copenhagen, Tårnby and Dragør). However, Frederiksberg has its own mayor and municipal council, and is fiercely independent.
