Metropolitan Police Department of the District of Columbia

The Metropolitan Police Department of the District of Columbia (MPDC), more commonly known locally as the Metropolitan Police Department (MPD), and, colloquially, DC Police, is the primary law enforcement agency for the District of Columbia, in the United States. With approximately 3,200 officers and 600 civilian staff, it is the sixth-largest municipal police department in the United States. The department serves an area of 68 square miles (180 km²) and a population of over 700,000 people. Established on August 6, 1861, the MPD is one of the oldest police departments in the United States. The MPD headquarters was formerly located at the Henry J. Daly Building, located at 300 Indiana Avenue NW in Judiciary Square across the street from the District of Columbia Court of Appeals and the Superior Court of the District of Columbia. However, in 2023, MPD moved into One Judiciary Square located at 441 4th St NW when the Daly Building started extensive renovation and refurbishment. The department's mission is to "safeguard the District of Columbia and protect its residents and visitors with the highest regard for the sanctity of human life". The MPD's regulations are compiled in title 5, chapter 1 of the District of Columbia Code.
