Karduansmakargatan, Pedestrian street in central Stockholm, Sweden.

Karduansmakargatan is a two-block street on Norrmalm in central Stockholm linking Malmtorgsgatan with Rödbodgatan and crossing Drottninggatan. Its buildings range from the Adelcrantz Palace, whose side facade faces the street, to the Ministry of Enterprise block built 1959–1961 by Nils Tesch, and a late-1970s office complex; two footbridges span the street. Its western section runs through a government quarter and is closed to the public.

The street takes its name from the karduansmakare, the leather tanners who worked in this part of Norrmalm in earlier centuries. Its present layout results from the Norrmalm redevelopment: the block between Rödbodgatan and Drottninggatan was rebuilt with government offices, and the editorial offices of Dagens Nyheter and Svenska Dagbladet along the street were demolished. The Adelcrantz Palace main building survived, with its side facade facing the street.

The name comes from the karduansmakare, the leatherworkers who once worked here. The street's west end runs through a government quarter and is now closed to the public. Two footbridges over the roadway link the office buildings on either side.

The street's western section runs through a government quarter and is closed to the public, so enter from the Drottninggatan or Rödbodgatan end. The eastern stretch between Drottninggatan and Malmtorgsgatan remains open and is crossed by two walkways linking the office buildings above.

The Ministry of Enterprise building on the south side was designed by Nils Tesch and built between 1959 and 1961. It has been blue-marked by the city, meaning it meets the criteria for a listed building under Sweden's Cultural Heritage Act. Two footbridges cross the street and connect the office complexes.
