Prior to settlement by colonists, Harwinton sat at the confluence of various tribal territories, notably that of the Tunxis tribe.[3] The Connecticut Colony granted and split the area of modern-day Harwinton to the townships of Hartford and Windsor in May 1729. The area was first settled in January 1730 by Daniel Messenger. Townships were formally established in the following years in the Hartford and Windsor allotments.
Harwinton was incorporated as an independent town in October 1737.[4][5] The name of the town alludes to Hartford and Windsor, Connecticut (HAR + WIN) followed by the suffix -ton, meaning town.[6]
