Saint-Gilles Prison (French: Prison de Saint-Gilles; Dutch: Gevangenis van Sint-Gillis) is a prison in Brussels, Belgium, that opened in 1884. It is located on the borders of the municipalities of Saint-Gilles, Ixelles and Forest, next to Forest Prison and Berkendael Prison.

Representative of the cellular system established during the 19th century, Saint-Gilles Prison was for a long time emblematic of overcrowding in Belgian prisons. Its infrastructure being in very poor condition, it was scheduled to close at the end of 2024, to be replaced by Haren Prison, but closure was postponed in February 2025, rescheduled for 2028.
