Lionel Tollemache, 5th Earl of Dysart (6 August 1734 – 20 February 1799), styled Lord Huntingtower until 1770, was an English peer.

Lord Huntingtower received no settlement from his father at his majority, and, feeling he owed him nothing, married without his knowledge or consent.

[1][2] The bride was Charlotte, daughter of Sir Edward Walpole, whom he married on 2 October 1760 at St James's Church, Piccadilly.

[3] Charlotte's uncle Horace Walpole called Huntingtower "a very handsome person".

Dysart remarried, on 19 April 1791, to Magdalene Lewis, sister of his brother Wilbraham's wife.
