Sir Arthur Chichester, 1st Baronet (c.1769–1847) was an Irish politician who represented Carrickfergus and Belfast in the Parliament of the United Kingdom, with the patronage of the Marquess of Donegall.
In 1812 Arthur Chichester defeated the Whig James Craig, with the Donegall interest that now was hostile to ministers.
He topped the poll of four candidates in the one-member constituency, in a close race with Ezekiel Davys Wilson.
He stood in Carrickfergus once more in 1832, as a reform Liberal, while at Belfast Lord Arthur Chichester took his place in the Donegall interest.
His views proving unpopular, he was kept out by the Tory Conway Richard Dobbs in a close contest.
