'Long Bridge') is a bascule bridge across the Inner Harbour of Copenhagen, Denmark, connecting Zealandside H. C. Andersens Boulevard to Amagerside Amager Boulevard.

It is one of only two bridges to carry motor vehicles across the harbour in central Copenhagen, the other being Knippelsbro.

Completed in 1690, the first bridge located roughly where Langebro is today was known as Kalvebodbro (Kalvebod Bridge) and connected the Western Rampart's Rysensteen Bastion on Zealand with Christianshavn Rampart's Christianshavns Vold#Kalvebod Bastion on Christianshavn.

It was a wooden structure with a drawbridge in the middle that allowed ships to pass.

The bridge was built for the military but was also open to civilian pedestrians.
