Westham is a suburb of Weymouth, Dorset, England.

Westham was established as a new suburb of Weymouth from the early 1880s.

[1] In 1880, the largely undeveloped Abbotsbury Road, along which Westham was centred, saw the construction of a number of residential properties, a chapel of ease, a schoolhouse and a steam laundry operated by the Weymouth Sanitary Steam Laundry Ltd.[2] The name Westham was decided upon during a meeting of "owners and holders of property in the district", held on 15 September 1882 at the Rock Hotel.

[5] In 2021, Westham Bridge Cycle Shelter was removed.

[6] The Westham ward elects members to Dorset Council.
