Gammel Kongevej (literally "Old King's Road) is the principal shopping street of Frederiksberg in Copenhagen, Denmark.

Gammel Kongevej is one of the oldest road sections in Frederiksberg, originally providing a direct connection between Copenhagen's Western City Gate and the historic village of Solbjerg (no longer in existence).

The road passed through open countryside with only a few scattered country houses until the mid-19th century when Copenhagen's fortifications were decommissioned and the city was allowed to develop freely.

A number of new country houses were built along the road but most of them were replaced by multi-story apartment buildings with shops in the ground floors in the 1880s and 1890s.

It is one of relative few examples of the many minor industrial enterprises that once dominated the courtyard of Copenhagen's Vesterbro and Nørrebro districts.

Just off Gammel Kongevej, between the streets H.C. Ørsteds Vej and Bülowsvej, is a small enclave which has been described as Denmark's first urban neighbourhood of single-family detached homes.
