John William Belcher (2 August 1905 – 26 October 1964) was a British Labour Party politician, who served as a trade minister in the post-Second World War Labour government. In February 1949, after an investigation into possible corrupt practices in the Board of Trade, Belcher resigned his ministerial and parliamentary offices when the Lynskey tribunal determined that he had misused his powers as a minister by granting favours in return for small gifts.
