The Metropolitan Correctional Center, San Diego (MCC San Diego) is the United States federal administrative detention facility in San Diego which holds up to 1048 male and female prisoners of all security levels. It is operated by the Federal Bureau of Prisons, a division of the United States Department of Justice. Most prisoners held at MCC San Diego have pending cases in the United States District Court for the Southern District of California. MCC San Diego also holds prisoners serving brief sentences. The 23 story building is connected via secure underground passageways to both the Schwartz and Carter/Keep Courthouses.

MCC San Diego opened in December 1974 and represented the first shift within the Bureau of Prisons to a new generation of high-rise prison buildings, along with MCC New York and MCC Chicago.
