The Blue Warehouse (Danish: Det Blå Pakhus), is an 18th-century warehouse located at Toldbodgade 36 on the Larsens Plads waterfront in Copenhagen, Denmark.

Completed in 1783 to the design of Caspar Frederik Harsdorff, it was converted into dwellings in the late 1970s.

The warehouse was originally intended for Royal Greenland, a chartered company responsible for trade on Greenland, but prior to its completion it was ceded to the Baltic-Guinea Company which had just been founded.

Designed by Caspar Frederik Harsdorff and built from 1781 to 1783, it was used for the storage of goods such as tobacco, sugar and cotton.

From 1978 to 1980 it was converted into condominiums by the architect Flemming Hertz (born 1936) and Ole Ramsgaard Thomsen (1937-2001).
