Nytorv 15/Rådhusstræde 2 is a Neoclassical property situated at the corner of Nytorv and Rådhusstræde in the Old Town of Copenhagen, Denmark. It consists of two separate buildings, the corner building from 1797 (Nytorv 15/Rådhusstræde 2) and an eight-bay building from 1798 (Rådhusstræde 2B), now connected by a narrow modern infill. The building was listed in the Danish registry of protected buildings and places in 1945. Notable former residents include jurist, writer and publisher Jacob Just Gudenrath (1657–1825), actors Stephan and Eline Heger, theatrical painter Edvard Lehmann and portrait painter hristian Frederik Christensen (1805-1883).

In the late 17th century, the site was made up of three smaller properties. The corner property was listed as No. 1 in the city's West Quarter, owned by blacksmith Niels Nielsen, in 1689. The adjacent property in Rådhustræde was, as No. 2, owned by vrager Rasmussen and No. 3 was owned by locksmith Anders Mikkelsen.

Nytorv 15 is constructed with four storeys over a walk-out basement. It has a three-bay facade towards the square, a five-bay facade towards Rådhusstræde and a chamfered corner bay. The latter was dictated for all corner buildings by Jørgen Henrich Rawert's and Peter Meyn's guidelines for the rebuilding of the city after the fire so that the fire department's long ladder companies could navigate the streets more easily. The plastered facade is finished with shadow joints below a belt course on the ground floor. Other decorative elements include projecting sills below the first floor windows, blond friezes between the central windows of the first and second floor, a triangular pediment above the first floor corner window, and a dentillated cornice.

The eight-bay-wide building at Rådhusstræde 2B is also constructed with four-storeys above a walk-out basement. The plastered facade is also finished here with a belt course, a blind frieze and a dentillated cornice. The narrow space between the two buildings has now been filled by a modern connector, with a door opening to a courtyard on the rear.

The building is owned today by E/F Nytorv 15/Rådhusstræde 2 A-C. It contains two condominiums on each floor, one in the corner building (Nytorv 15) and one in the Rådhusstræde wing (Rådhusstræde 2).
