Garches (French pronunciation: [ɡaʁʃ] ⓘ) is a commune in the western suburbs of Paris, France.

Garches has remained largely residential, with a population of 17,898 as of 2021, but is also the location of Raymond Poincaré University Hospital, which specialises in traumatology, road accidents and physiotherapy.

The northern part of Garches was largely destroyed in the Battle of Buzenval on 19 January 1871, when besieged Parisian forces under Louis Jules Trochu attempted to break through the German blockade and join the French troops at Versailles.

The spire was rebuilt in 1988, the cross reconsecrated in 1989, the carved tympanum restored in 1990, and interior and façade renovation carried out beginning in 1995.

[6] The cemetery adjacent to the church was moved in 1930 and contains the graves of some well-known people, including jazz musician Sidney Bechet, who chose to spend his last years in Garches.
