Viscount Chaplin

Viscount Chaplin, of Saint Oswald's, Blankney, in the County of Lincoln, was a title in the Peerage of the United Kingdom. It was created in 1916 for Henry Chaplin, a Tory MP, cabinet minister, country landowner and racehorse owner. The title became extinct upon the death of his grandson, the third Viscount, in 1981.

Edith Chaplin, daughter of the first Viscount, married Charles Vane-Tempest-Stewart, 7th Marquess of Londonderry, and became a well-known socialite and philanthropist. Edward Chaplin, younger brother of the first Viscount, was also a politician. The Chaplin family descended from Sir Francis Chaplin, Lord Mayor of London from 1677 to 1678. Sir Francis was the father of Robert Chaplin, who was created a baronet in 1715 (see Chaplin baronets), and John Chaplin, ancestor of the Viscounts Chaplin.
