The 1924 Holland with Boston by-election was a by-election held on 31 July 1924 for the British House of Commons constituency of Holland with Boston in Lincolnshire.

The by-election was caused by the death of the town's Labour Member of Parliament (MP) William Stapleton Royce, who had held the seat since its creation for the 1918 general election. The Liberal candidate was the son of Sir Richard Winfrey, MP for South West Norfolk from 1906–1923 and Gainsborough from 1923-24.

The result was a victory for the Conservative Party candidate Arthur Dean.^[1]
