Arthur Saunders Gore, 2nd Earl of Arran, KP, PC (Ire), styled The Honourable Arthur Gore from 1758 to 1762 and Viscount Sudley from 1762 to 1773, was an Irish peer and politician.

Earl of Arran is a title in the Peerage of Ireland. It is not to be confused with the title Earl of Arran in the Peerage of Scotland. The two titles refer to different places: the Aran Islands in Ireland, and the Isle of Arran in Scotland. The Irish earldom is held by the Gore family. The Scottish earldom is a separate title, held as a subsidiary title of the Duke of Hamilton.
