Nyhavn 11 is an 18th-century property overlooking the Nyhavn canal in central Copenhagen, Denmark. Ludvig Ferdinand Rømer established a sugar refinery on the property in 1653 and it was later continued by changing owners until at least the 1860s. A small figure of a sugar-baker holding a sugar cone is still seen above the gate. The building was listed in the Danish registry of protected buildings and places in 1932. Notable former residents include the general trader Jacob Severin and actors Christen Niemann Rosenkilde, Julie Sødring and Poul Reumert. The lamp manufacturer Louis Poulsen was later based in the building from 1908 to 2006.
