Phalsbourg (French pronunciation: [falsbuʁ]; German: Pfalzburg; Lorraine Franconian: Phalsburch) is a commune in the Moselle department in Grand Est in north-eastern France, with a population of about 5,000.

In 1570, Duke George John I, Count Palatine of Veldenz founded the town of Pfalzburg as a refuge for Reformed Protestants expelled from the Duchy of Lorraine, and as an administrative center of his holdings.

In 1608, his successor Georg Gustav of Palantine Veldenz founded nearby Lixheim for Reformed refugees, but was also forced to sell the new town in 1623 to Lorraine.

The fortifications of Phalsbourg resisted the Allies in 1814 and 1815, and the Germans commanded by Taillant for four months during 1870, but they were taken on 12 December of that year, and have since been razed.

Johann Wolfgang von Goethe visited the town on 23 June 1770,[3] and mentioned his stay in his autobiography Dichtung und Wahrheit.
