Richard Hobart FitzGibbon, 3rd Earl of Clare (2 October 1793 – 10 January 1864) was an Anglo-Irish politician and noble.

Born at Mountshannon House in County Limerick, FitzGibbon was educated at Harrow School.^[1] He joined the British Army, and was present at the Second Battle of Porto and Battle of Talavera.^[2]

At the 1818 UK general election, he stood in County Limerick for the Whigs, winning the seat. He rarely spoke in Parliament, and did not always vote in line with the Whig leadership. In turn, they offered him little support, but he nevertheless held his seat, sometimes describing himself as an independent. He served until 1841, when he stood down.^[2] He was appointed Governor of Limerick in 1818, and later served twice as Lord Lieutenant of Limerick.

In the 1820s, FitzGibbon had a child with Diana Woodcock, who was then married to Maurice Crosbie Moore. He obtained a divorce in 1825, by act of the House of Lords, and FitzGibbon and Woodcock immediately married. However, Moore secured custody of FitzGibbon's illegitimate child, despite stating that he was doing so purely out of vindictiveness. The couple had one legitimate child, John Charles Henry FitzGibbon, Viscount FitzGibbon, who was killed in the Battle of Balaklava in 1854.^[1] In 1851, FitzGibbon succeeded his brother as the Earl of Clare. He died in 1864.^[2]
