Sir John Eccles (c.1664 – 1727) was an Anglo-Irish merchant and landowner.
Eccles was the son of John Eccles of Malone, Belfast and Elizabeth Best of Hornby Castle, Lancashire. His father, a Protestant settler born in Scotland, had given shelter to William III of England during a storm prior to the Battle of the Boyne.[1][2]
He was a merchant based in Dublin, and owned an extensive estate called "Mount Eccles" in the area that is now North Great George's Street.[3] In 1710, he was appointed Lord Mayor of Dublin.[4] On 16 November 1714 he was knighted at St James's Palace, London. Between 1725 and his death he was a justice of the peace for the city. He was patron of the Old Church of St George, Hill Street Dublin.
Eccles Street in Dublin was named in his honour.
