Middlesex County is governed by a Board of Chosen Freeholders, whose seven members are elected at-large on a partisan basis to serve three-year terms of office on a staggered basis, with either two or three seats coming up for election each year as part of the November general election.
At an annual reorganization meeting held in January, the board selects from among its members a Freeholder Director and Deputy Director.
Portions of the township were taken to form Rahway (April 19, 1858), Raritan Township (March 17, 1870, now Edison Township) and Roosevelt (April 11, 1906, now Carteret).
