The Bristol Bus Boycott of 1963 arose from the refusal of the Bristol Omnibus Company to employ Black or Asian bus crews in the city of Bristol, England. In line with many other British cities at the time, there was widespread racial discrimination in housing and employment against so-called "Coloureds". An organisation founded by Roy Hackett and led by youth worker Paul Stephenson as the spokesperson of the group which included Owen Henry, Audley Evans, Prince Brown and Guy Bailey and the West Indian Development Council, the boycott of the company's buses by Bristolians lasted for four months until the company backed down and overturned their discriminative colour bar policy.

The boycott drew national attention to racial discrimination in Britain and the campaign was supported by national politicians, with interventions being made by church groups and the High Commissioner for Trinidad and Tobago. The Bristol Bus Boycott was considered by some to have been influential in the passing of the Race Relations Act 1965 which made "racial discrimination unlawful in public places" and the Race Relations Act 1968, which extended the provisions to employment and housing.
