Neue Sorge, also known as Königstraße or Königstrasse after its main boulevard, was a quarter of eastern Königsberg, Germany. Its territory is now part of the Leningradsky District of Kaliningrad, Russia.
The original name Neue Sorge was derived from the Old Prussian zarge, meaning enclosed fields, or sarge, meaning sentinel or watchman. In folk etymology, the German language name derived from the response of Bogusław Radziwiłł, 17th century governor of Königsberg, when asked what the developing district should be called: "Wieder eine neue Sorge!" ("Again a new worry!"). The later name Königstraße means "King Street" in German.
At the start of the ducal era, the pathway led to pastures for cattle and horses known as the Kalthöfischer Acker. Settlement began ca. 1610, and in 1612 fields were granted to numerous high-ranking ducal officials. In 1662 Duke Frederick William, the Great Elector, established Neue Sorge as a Freiheit of Königsberg Castle and bestowed it with a Gerichtssiegel, or court seal. This depicted a hand descending from clouds holding a heraldic right angle, flanked by two open eyes, as well as the 1662 year of its granting.
Neue Sorge was bordered by Löbenicht to the west, Rossgarten to the north, the 17th century Baroque city walls to the east, and Sackheim to the south. The residents of Neue Sorge attended Altrossgarten Church. In 1729 Neue Sorge was documented as Königstraße, a street which ran from Roßgarten's market to a cul-de-sac at King's Gate.
