Viscount Cobham is a title in the Peerage of Great Britain. It was created in 1718 for Field Marshal Sir Richard Temple, 1st Baron Cobham and 4th Baronet, of Stowe. The Viscount holds the subsidiary titles of Baron Cobham, of Cobham in the County of Kent, (1718), Baron Westcote, of Ballymore in the County of Longford (1776), and Baron Lyttelton, of Frankley in the County of Worcester (1794). All the titles are in the Peerage of Great Britain, except the barony of Westcote, which is in the Peerage of Ireland. The Viscount is also a Baronet, of Frankley in the County of Worcester (1618).
The barony and viscountcy of Cobham were subsidiary titles of the earldom of Temple from 1750 to 1784, of the Marquessate of Buckingham from 1784 to 1822 and of the Dukedom of Buckingham and Chandos from 1822 to 1889. Since the latter year the titles are merged with the barony of Lyttelton and barony of Westcote.
