Southampton Citybus was a bus operator which operated local services throughout the English city of Southampton. It was formed in 1898 as Southampton Corporation Transport. In 1986, as a result of deregulation an 'arms-length' limited company was formed in the name of Southampton Citybus and the coat of arms of the City of Southampton was removed, and replaced with the new branding. The company was owned by the town council until 1954, and the city council until 1993. It was then bought by its employees, in 1997 it was purchased by FirstGroup and is now part of First Hampshire & Dorset.
