About Us


Originally created by an Act of the Legislature in 1911, the Middlesex County Retirement System is the fourth largest of the 104 retirement systems in the Commonwealth. We provide retirement, disability and survivor benefits to approximately 6,000 retirees and 10,000 active employees of 31 Towns and 40 Districts and Authorities within Middlesex County.

The mission of the Middlesex County Retirement Board is to provide secure retirement benefits lawfully earned through public service to the members and beneficiaries of the Middlesex County Retirement System, and to administer those benefits with the highest degree of prudence, integrity and fiscal responsibility.
