Tunbridge was originally a coaching stop on the Hobart to Launceston road, now known as the Midland Highway. It was named after one of its three original coaching inns, the Tunbridge Wells, which in turn was named after Tunbridge Wells in Kent, England.

In its coaching heyday it had three coaching inns, the Tunbridge Wells Inn, the Victoria Inn and the York Inn. Each inn was associated with a different coaching company. The Tunbridge Wells serviced J. E. Cox Coaches, the Victoria Inn serviced Samuel Page Coaches and the York Inn serviced Alfred Burbury Coaches. Tunbridge Post Office opened in 1856.

Tunbridge was gazetted as a locality in 1974.
