George Whiteley, 1st Baron Marchamley PC (30 August 1855 – 21 October 1925) was a British Conservative turned Liberal Party politician.

[1][2][4] He became Parliamentary Secretary to the Treasury (Chief Whip) when the Liberals came to power in December 1905,[1] and was made a Privy Counsellor in 1907.

[10] The Complete Peerage summarised up his oratory as: "A ready speaker, with a somewhat caustic humour, he was on the platform an effective asset to the Liberal Party".

[11] Lord Marchamley married Alice, only child of William Tattersall, JP, of Quarry Bank, Blackburn, and St Anthony's Milnthorpe, in 1881.

Marchamley survived her by twelve years and died at his home, 29 Princes Gardens, London,[2] after an operation[13] in October 1925, aged 70.
