The Collin House (Danish: Den Collinske Gård) is a listed Neoclassical property at Amaliegade No.

It takes its name after Jonas Collin, a prominent civil servant and leading patrons of the arts during the Danish Golden Age, who owned the building from 1838 to 1861.

Allegedly, Jonas Collin decided to move when it rained through the ceiling and onto the table in the presence of Bertel Thorvaldsen.

[4] On 3 October, Collin arranged a housewarming which was attended by some of the leading Danish artists of the time, including Bertel Thorvaldsen and Hermann Ernst Freund, Johan Ludvig, Hans Christian Andersen and Johanne Luise Heiberg.

[7] The building was later home to the company M.J. Grønbech & Sønner whose old headquarters at Bag Børsen 76 was demolished in connection with an expansion of Slotsholmen.

It is pulled back from the street and thus breaks fundamentally with Nicolai Eigtved's strict guidelines for the architecture of Amaliegade and Frederiksstaden.
