William Russell (9 November 1798 – 30 January 1850) of Brancepeth Castle in County Durham was a British Whig politician. He sat in the House of Commons between 1822 and 1832.
He was elected at a by-election in 1822 as one of the two Members of Parliament (MPs) for borough of Saltash in Cornwall. He held that seat until the 1826 general election, when he was returned as an MP for the borough of Bletchingley in Surrey. He resigned the Bletchingley seat in 1827 (by taking the Chiltern Hundreds) to stand at a by-election for County Durham, where he was returned without a contest. He held the Durham seat until the constituency was divided at the 1832 general election.
He was High Sheriff of Durham in 1841.
