The Ripon by-election, 1925 was a parliamentary by-election held on 5 December 1925 for the British House of Commons constituency of Ripon.
The by-election was a consequence of the sitting MP Edward Wood (later the 1st Earl of Halifax) being elevated to the peerage as Baron Irwin in order to serve as Viceroy of India. Wood had served Ripon as a Conservative since 1910.
Two candidates were nominated. The winning candidate was the Conservatives' John Waller Hills, who had represented the City of Durham until he was defeated by the Labour candidate in the 1922 General Election. He was opposed in the by-election by the Liberal candidate John Murray, another former MP who had lost his seat to Labour in the 1923 General Election in Leeds West; Murray had subsequently fought unsuccessfully in the Kirkcaldy District of Burghs constituency in the 1924 General Election. There was no Labour candidate.
Hills was to remain MP for Ripon until his death in 1939.
