The Borough of Tunbridge Wells is a local government district with borough status in Kent, England. It takes its name from its main town, Royal Tunbridge Wells. The borough also contains the towns of Paddock Wood and Southborough, along with numerous villages and surrounding rural areas. Large parts of the borough fall within the High Weald Area of Outstanding Natural Beauty.

Royal Tunbridge Wells is a town in Kent, England, 30 miles southeast of central London. It lies close to the border with East Sussex on the northern edge of the High Weald, whose sandstone geology is exemplified by the rock formation High Rocks. The town was a spa in the Restoration and a fashionable resort in the mid-1700s under Beau Nash when the Pantiles, and its chalybeate spring, attracted visitors who wished to take the waters. Though its popularity as a spa town waned with the advent of sea bathing, the town still derives much of its income from tourism.
