Arthur Chichester, 1st Earl of Donegall (16 June 1606 – 18 March 1675), was an Anglo-Irish military officer, politician and peer.
He made a career as a soldier before being elected to the Irish House of Commons as Member of Parliament for Antrim in 1634 and again in 1640.
Having distinguished himself in helping to put down the rebellion which took place in Ulster in 1641, Chichester was admitted to the Privy Council of Ireland in 1643.
The earldom was created with a special remainder to the male heirs of his father, whom he succeeded a year later as Viscount Chichester and Governor of Carrickfergus for life.
[1] He married three times: Lord Donegall died after a short illness in Belfast in 1675 and was buried in St Nicholas's Church, Carrickfergus.
