Lyme is a town in New London County, Connecticut, United States, situated on the eastern side of the Connecticut River. The population was 2,352 at the 2020 census. Lyme is the eponym of Lyme disease. History In February 1665, the portion of the territory of the Saybrook Colony east of the Connecticut River was set off as the plantation of East Saybrook, which included present-day Lyme, Old Lyme, and the western part of East Lyme. In 1667, the Connecticut General Court formally recognized the East Saybrook plantation as the town of Lyme, named after Lyme Regis, a coastal town in the south of England. The eastern portion of Lyme (bordering the town of Waterford) separated from Lyme in 1823 and became part of East Lyme. The southern portion of Lyme (along Long Island Sound) separated in 1855 as South Lyme (renamed Old Lyme in 1857). Both changes were consistent with the then-existing laws of the state of Connecticut.
