Admiralgade 23 is a Neoclassical property situated at the corner of Admiralgade and Dybensgade in central Copenhagen, Denmark. It was together with the adjacent building at Dybensgade 21 constructed for goldsmith Christian Nielsen Lindbach after the previous buildings at the site had been destroyed in the Copenhagen Fire of 1795. The two properties were merged into a single property in 1981. They were jointly listed in the Danish registry of protected buildings and places in 1945.
