Ursus is a district (dzielnica) of Warsaw, one of the 18 such units into which the city is divided.
In the area that is today Ursus, there were three villages in the 14th century: Czechowice, Skorosze and Szamoty (later called Gołąbki).
Skorosze became the seat of the municipality, and in the early 1920s the Szamoty area's Zakłady Mechaniczne "Ursus" (English: Ursus Industrial Plants) (makers of agricultural machinery) were built.
It was the signal that started Komitet Obrony Robotników (KOR), a movement which was successful in uniting the workers and intellectuals against the communist government, which eventually led to the birth of the Solidarity movement.
On August 1, 1977, Ursus became part of Warsaw within the Ochota district as punishment for the strikes in June 1976.
