Kamienica Pod Murzynkiem, Tenement house in Old Town Market Square, Warsaw, Poland.

Kamienica Pod Murzynkiem is a tenement house on the northern edge of the Old Town Market Square, part of the protected historic district. The three-story building features typical Warsaw architecture with symmetrically arranged windows and a street-level arcade for shops.

First recorded in 1449 as the Sycz family house, it was rebuilt from 1622 to 1628 for royal carver Jan Klug by Gerard Kleinpoldt and completed by Jakub Gianotti, gaining four storeys, an attic and the Moor's head. In 1945 it was the least damaged building on the Old Town Market Square; reconstruction restored the facade head.

The name 'Pod Murzynkiem' refers to the carved head of a Black man on the facade, added during the 1622–1628 rebuilding commissioned by Jan Klug and finished by Jakub Gianotti. The house is also known as Imlandowska, Dzianottowska and Ginterowska, after former owners. In 1951 a plaque to Feliks Dzierżyński, who spoke here at a workers' meeting in 1899, was unveiled; it was removed in 1990.

The building sits centrally on the Old Town Market Square and is easy to reach on foot through the pedestrian zone. Visitors can view the exterior from the square, but the interior is typically private or only open during special occasions.

The name comes from the head of a Black man carved on the facade, added during the 1622–1628 rebuild by Jan Klug and completed by Jakub Gianotti. The head was reconstructed after the war, and a plaque to Felix Dzierżyński, unveiled in 1951, was removed in 1990.
