Richard Crawshaw, Baron Crawshaw of Aintree, known as Dick Crawshaw (September 25, 1917—July 16, 1986) was elected as a British Labour Party Member of Parliament in 1964 but left, or "defected" as the media reported to join the SDP in 1981. Crawshaw was a strong supporter of the Territorial Army and on one occasion voted against the annual Defence Estimates because they failed to make a large enough provision for it.

He was later raised to the peerage as Baron Crawshaw of Aintree, of Salford in the County of Greater Manchester. He was reported to have been a very diligent constituency MP who personally visited the homes in his Liverpool constituency of Toxteth calling on the homes in several streets each week, to the surprise of the residents.
