Arthur Chichester, 1st Marquess of Donegall (13 June 1739 – 5 January 1799), known as Arthur Chichester until 1757 and as The Earl of Donegall between 1757 and 1791, was an English nobleman and politician in Ireland.

Early life
Chichester was born on 13 June 1739. He was the son of Hon. John Chichester and Elizabeth Newdigate (1703–1769), eldest daughter of Sir Richard Newdigate, 3rd Baronet. His paternal grandparents were Arthur Chichester, 3rd Earl of Donegall and Lady Catherine Forbes (a daughter of the 1st Earl of Granard), in 1726.

He was educated at Westminster School in 1748 and Trinity College, Oxford, matriculating in 1757, before succeeding his uncle in 1757 as fifth Earl of Donegall.

Career
After taking his seat in the Irish House of Lords in 1765, Donegall served at Westminster as Member of Parliament for Malmesbury (1768–1774) by his friend Lord Suffolk, first following Suffolk and the Grenville group. Reportedly, he never spoke in the House, and did not stand for reelection in 1774.

As a means of securing his support for the Government in the Irish House of Commons, he was in 1790 created Baron Fisherwick, of Fisherwick in the County of Stafford, in the Peerage of Great Britain. The following year he was also created Earl of Belfast and Marquess of Donegall in the Peerage of Ireland.
