The January 1910 United Kingdom general election was held from 15 January to 10 February 1910. The government called the election in the midst of a constitutional crisis caused by the rejection of the People's Budget by the Conservative-dominated House of Lords, in order to get a mandate to pass the budget.

The 1909/1910 People's Budget was a proposal of the Liberal government that introduced unprecedented taxes on the lands and incomes of Britain's wealthy to fund new social welfare programmes. It passed the House of Commons in 1909 but was blocked by the House of Lords for a year and became law in April 1910.
