Alf Cock-Clausen (2 March 1886 – 10 July 1983) was a Danish architect. He was active during the transition from Neoclassicism to Functionalism and many of his works show influence from Art Deco. His factory for the distillery De Danske Spritfabrikker at Aalborg's harbour front was declared a Danish Industrial Heritage Site in 2009. Other works include the headquarters of publisher Guttenberghus (now ), now partly converted into the Danish Film Institute, and the Richshuset in Copenhagen.
