Frederiksholms Kanal is a canal in central Copenhagen, Denmark, which runs along the south-west side of Slotsholmen, together with Slotsholmskanalen separating the island from Zealand.

Several historic buildings face the canal, ranging in size from Prince's Mansion, now housing National Museum, and Christiansborg's riding grounds to the diminutive Stable Boy's House, part of Civiletatens Materialgård, a former storage facility now used by the Royal Danish Academy of Fine Arts's School of Sculpture.

To better protect Slotsholmen, at that time home both to the royal palace and the fleet, the West Rampart was extended well into the sea.

[1] Part of the new Frederiksholm area was used for the storage of building materials which were used in the construction work, both military and civilian, which was constantly ongoing in the expanding city.

The military storage facility Fæstningens Materialgård was established shortly after Frederiksholms Kanal had been dug but none of the original buildings exist today.

A few buildings on the Slotsholmen side of the canal also addressed on Frederiksholms Kanal, including Staldmestergården and the small Faroese Warehouse.

The building will houseDanish Architecture Centre, now based in Gammel Dok on the other side of the harbour, as well as offices and dwellings.

The old main entrance and one of few surviving features of the first Christiansborg Palace which burned in 1794, the bridge was constructed from 1739 to 1745 with Nicolai Eigtved as principal architect.
