Brolæggerstræde (literally "Cobble-Layer Alley) is a street in the Old Town of Copenhagen, Denmark, linking Nytorv in the west with Badstuestræde in the east.

[2] Knabrostræde connected the south side of the street to the coast at Gammel Strand.

Endeløsstræde ("Endless Alley"), a short cul-de-sac, extended northwards a little further to the east.

When the street was rebuilt following the Copenhagen Fire of 1728, Knabrostræde was extended northwards to Vimmelskaftet and Endeløsstræde was later connected to its east side.

Brygger, kaptajn J. C. Jacobsen foretog her året 1838 de første forsøg med fremstilling af undergæret øl".

The building was refurbished by the architect Viggo Steen Møller in the early 1950s and now houses the Ny Carlsberg Foundation.

11 on the opposite side of the street was built for another brewer, Andreas Tronier.

A brass plaque to the left of the gate commemorates the Danish Confederation of Trade Unions which had its first home in the building from 1898 until 1950.
