Fredericiagade (Danish pronunciation: [fʁeðəˈʁetɕæˌkɛːðə]) is a street in central Copenhagen, Denmark.

Fredericiagade traces its history back to Christian IV's foundation of Nyboder naval barracks in 1631 but different sections of it were then known under individual names.

The section from Kronprinsessegade to Rigensgade was called Kokkegade (Cook Street).

The new name was chosen to honour the town of Fredericia for its role in the Three Years' War.

It was originally built as opera house from Frederick IV in 1701-02 and was either designed by W.F.
