Earl of Glasgow is a title in the Peerage of Scotland. It was created in 1703 for David Boyle, Lord Boyle, one of the commissioners who negotiated the Treaty of Union uniting the Kingdom of England and the Kingdom of Scotland into the United Kingdom of Great Britain. He had already been created Lord Boyle of Kelburn, Stewartoun, Cumbrae, Finnick, Largs and Dalry in 1699, and was made Lord Boyle of Stewartoun, Cumbraes, Fenwick, Largs and Dalry and Viscount of Kelburn at the same time as he was granted the earldom. These titles are also in the Peerage of Scotland. The fourth Earl was created Baron Ross, of Hawkhead in the County of Renfrew, in the Peerage of the United Kingdom, a title which became extinct on the death of the sixth Earl in 1890. The seventh Earl served as Governor of New Zealand from 1892 to 1897 and was created Baron Fairlie, of Fairlie in the County of Ayr, in the Peerage of the United Kingdom, in 1897.
The Earl of Glasgow is the hereditary Clan Chief of Clan Boyle.
The family seat is Kelburn Castle in Ayrshire, Scotland.
The heir apparent is the present holder's son David Michael Douglas Boyle, Viscount of Kelburn (b. 1978).
