William Willoughby Cole, 1st Earl of Enniskillen (1 March 1736 – 22 May 1803), styled The Honourable from 1760 to 1767, then known as the Lord Mountflorence to 1776 and as the Viscount Enniskillen to 1789, was an Irish peer and politician.
Enniskillen was the eldest son of John Cole, 1st Baron Mountflorence of Florence Court, County Fermanagh.
Cole represented Enniskillen in the Irish House of Commons from 1761 to 1767, when he succeeded his father as 2nd Baron Mountflorence and took his seat in the Irish House of Lords. In 1776, he was created Viscount Enniskillen and in 1789 he was even further honoured when he was made Earl of Enniskillen. Both these titles are in the Peerage of Ireland.
