Christianshavns Vold is a former rampart which was part of the bastioned fortification ring which used to surround Copenhagen, Denmark. Running along the full south-eastern perimeter of Christianshavn and Holmen, it used to form a protective barrier towards the island of Amager. It consists of earthworks with 12 bastions and in front of it ran a moat, Stadsgraven, now forming a broad canal which separates Christianshavn from the rest of Amager. Along with Kastellet on the other side of the harbour, it is the only intact part of the fortification system.

Today Christianshavns Vold serves as an important greenspace for Christianshavn's inhabitants. The southern half of the rampart is a municipal park whereas the northern portion is part of Freetown Christiania, a self-built, semi-autonomous community which has existed since the early 1970s.
