Charles Robert Spencer, 6th Earl Spencer, (30 October 1857 – 26 September 1922), styled The Honourable Charles Spencer until 1905 and known as The Viscount Althorp between 1905 and 1910, was a British courtier and Liberal politician from the Spencer family. An MP from 1880 to 1895 and again from 1900 to 1905, he served as Vice-Chamberlain of the Household from 1892 to 1895. Raised to peerage as Viscount Althorp in 1905, he was Lord Chamberlain from 1905 to 1912 in the Liberal administrations headed by Sir Henry Campbell-Bannerman and H. H. Asquith. In 1910, he succeeded his half-brother in the earldom of Spencer. He was married to Margaret Baring, a member of the Baring family. They were great-grandparents of Diana, Princess of Wales.
