The answer to what county Colchester CT is in is simple: Colchester belongs to New London County. The town sits in eastern Connecticut, with Hartford to the northwest, Norwich and New London to the southeast, and the Connecticut shoreline within a practical drive.
The small wrinkle is Connecticut itself. Connecticut’s historic counties still appear on forms, maps, weather alerts, real estate records, and search results, but county government does not run daily local services the way it does in many other states. For most town matters, Colchester handles services locally through the Town of Colchester.

Why Colchester Gets Confused With Other Connecticut Counties
Colchester gets confused with nearby counties because the town sits near the edge of New London County, not deep inside the county’s coastal core. Colchester is inland, rural in feel, and closer to Hartford than many people expect from a New London County town.
Road maps can add to the mix-up. Route 2 ties Colchester to Hartford in one direction and Norwich in the other. East Haddam and Haddam sit to the west in Middlesex County, while Lebanon and Norwich sit east or southeast in New London County.
The most reliable way to think about Colchester is this: Colchester is an inland New London County town with quick road access to both central Connecticut and the eastern Connecticut shoreline.
Does Connecticut Still Use Counties For Colchester?
Connecticut still uses county names such as New London County in many records and public tables, but Connecticut counties do not operate as normal county governments. Colchester’s town government is the better place to start for local town services.
The Connecticut Secretary of the State town-and-county table lists COLCHESTER under New London County and gives town-level area and population figures.
For travelers, the county question mostly matters for orientation. For residents or researchers, the county question matters for older records, statewide datasets, property context, and forms that still ask for a county. For town business, Colchester Town Hall is the local anchor.
