John Savile, 2nd Earl of Mexborough, styled Viscount Pollington between 1766 and 1778, was a British peer and politician.
Mexborough was the son of John Savile, 1st Earl of Mexborough, and Sarah (née Delaval).
Mexborough succeeded his father in the earldom in 1778. However, as this was an Irish peerage it did not entitle him to a seat in the British House of Lords (although it did entitle him to a seat in the Irish House of Lords). In 1808 he was elected to the House of Commons for Lincoln, a seat he retained until 1812.
Lord Mexborough married Elizabeth, daughter of Henry Stephenson, in 1782.
