Major Cities Chiefs Association

Organization Abbreviation: 

Major Cities Chiefs Association (MCCA) is a professional association of chiefs and sheriffs representing the largest cities in the United States, Canada, and the United Kingdom (UK). MCCA membership is comprised of chiefs and sheriffs of the 66 largest law enforcement agencies in the United States, nine largest in Canada, and one in the UK. They serve 82.5 million people with a sworn workforce of 190,402 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:

  • Influencing national public policy on law enforcement matters,
  • Enhancing the development of current and future leaders, and
  • Encouraging and sponsoring 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.
