Monroe is a town located in eastern Fairfield County, Connecticut, United States. The population was 18,825 at the 2020 census. The town is part of the Greater Bridgeport Planning Region.

Monroe is largely considered a bedroom community of New York City, New Haven, and Bridgeport.

On May 15, 1656, the Court of the Colony of Connecticut in Hartford affirmed that the town of Stratford included all of the territory 12 miles (19 km) inland from Long Island Sound, between the Housatonic River and the Fairfield town line, to include the southern portion of present-day Monroe. In 1662, Stratford selectmen Lt. Joseph Judson, Captain Joseph Hawley and John Minor secured all the written deeds of transfer from the Golden Hill Paugussett Indian Nation for this vast territory that comprises the present-day towns of Trumbull, Shelton and Monroe. In 1671, Stratford purchased from the Paugusset Indians the territory which included the remainder of the northern portions of Monroe, Trumbull and Shelton, in what is known as "The White Hills Purchase", and officially annexed it to the Township of Stratford.

Monroe incorporated as a town in 1823. The community is named after James Monroe, fifth President of the United States.

On August 18, 2024 the town suffered from a flash flood which poured over 10 inches of rain on the town, causing many roads in town to flood and wash out, leaving many stranded. This included the Route 34 bridge near the Lake Zoar drive in getting washed away completely, leaving the road closed for an extended period of time.
