Sir John Frederick Ellenborough Crowder (10 November 1891 – 9 July 1961) was a Conservative Party politician in the United Kingdom.
He served with the Lincolnshire Yeomanry from 1914 to 1918, when he transferred to the Reserve Regiment of the Royal Horse Guards.
He served again during World War II, as a staff captain and army welfare officer.
He appears as a character in The Long Walk to Finchley, on Thatcher's selection to succeed him as Conservative candidate for his seat – he is played, in a less than flattering yet accurate light, by Geoffrey Palmer.
