Neurossgarten (German: Neuroßgarten) was a quarter of northwestern Königsberg, Germany. Its territory is now part of Kaliningrad, Russia.
The name Neuroßgarten means "new horse pasture" in German, with the eastern Königsberg suburb of Rossgarten (or Altroßgarten) being its namesake. The area of Neurossgarten was first mentioned as the Altstädtischer Roßgarten in 1466 in archives of the Teutonic Knights, and consisted of meadows, pastures, gardens, and a cemetery used by Steindamm. Neurossgarten was established as a new suburb of Altstadt separate from Steindamm in 1635.
By the Rathäusliche Reglement of 13 June 1724, King Frederick William I of Prussia merged Altstadt and Neurossgarten into the united city of Königsberg. By 1890 the area from Neurossgarten's Wagnerstraße through Steindamm to Tragheimer Pulverstraße was the most densely settled part of the city. The quarter was heavily damaged by the 1944 Bombing of Königsberg and 1945 Battle of Königsberg.
Neurossgarten was bounded by Steindamm to the east and Laak to the south. To the west and north were the streets Deutschordensring (formerly Krausenecksche Wallstraße) and Kniprodestraße (formerly Alte Gasse), followed by the early 17th century Baroque city walls. Beyond the walls was Mittelhufen.
Neurossgarten Church was a 17th-century Protestant church located in central Neurossgarten. Nearby marketplaces included the Strohmarkt and the Heumarkt.
