Fürstenfeldbruck is a Landkreis (district) in Bavaria, Germany. It is bounded by (from the east and clockwise) the city of Munich and the districts of Munich, Starnberg, Landsberg, Aichach-Friedberg and Dachau.

In medieval times the region was a clerical state ruled by the abbey of Fürstenfeld. When the clerical states of Holy Empire were dissolved in 1803, the territory was annexed by Bavaria. The district of Fürstenfeldbruck was established in 1939.

The district is occupied by the western Munich metropolitan area. It has the highest population density of all Bavarian districts. More than 90 percent of the population lives in the eastern half of the district, which includes the suburbs of Munich.

• The red and white bar is from the family arms of Saint Bernard, who had been the founder of the Cistercian order (Fürstenfeld was a Cistercian monastery)
• The crown is from the arms of the abbot Alexander Pellhammer
• The bridge represents the city of Bruck (which was later merged with Fürstenfeld to form the city of Fürstenfeldbruck)
