Welcome to the Major Cities Chiefs Association (MCCA) website. MCCA is a professional association of Chiefs and Sheriffs representing the largest cities in the United States, Canada and the UK. MCCA membership is comprised of Chiefs and Sheriffs of the sixty-six largest law enforcement agencies in the United States, nine largest in Canada and one in the UK. They serve 82.5 million people (69.5 US - 10.5 Canada - 2.5 UK) with a sworn workforce of 190,402 (161,664 US, 20,506 Canada, 8232 UK) officers and non-sworn personnel.

MCCA was formed in 1949 to provide a forum for executives to share ideas, experiences and strategies for addressing the challenges of policing large urban communities. While the forum remains a primary purpose, as MCCA has grown its purpose has expanded to include:

  • To influence national public policy on law enforcement matters
  • To enhance the development of current and future leaders
  • To encourage and sponsor research

MCCA's U.S. members are very active in advisory roles to the Department of Justice, the Department of Homeland Security, the Department of Defense, and are frequently invited to testify before Congress. Our Canadian and UK members serve in similar roles in their countries.

Navigate through our website to learn more about our member cities, our leadership, and our positions on modern policing issues and best practices.
