Edmund George Lamb MA FCS FRGS (8 July 1863 – 3 January 1925) was an English landowner, colliery proprietor, and radical Liberal Party politician.
He was the son of Richard Westbrook Lamb JP DL of West Denton, Northumberland and Georgiana Eaton of Ketton Hall, Rutland. He was educated at Oratory School, Edgbaston and Merton College, Oxford where he received a Master of Arts and finally University College, London. In 1893 he married Mabel Winkworth (1862–1941), daughter of a Manchester cotton mill owner. They had one child, Winifred Lamb (1894–1963). She was a classical archaeologist, and author of several works on ancient Greece.
Lamb was a colliery proprietor in Northumberland, and a landowner in Northumberland and Sussex. He was a Fellow of the Chemical Society. He was a Fellow of the Royal Geographical Society.
He was elected at the 1906 general election as the Liberal Member of Parliament (MP) for the Leominster division of Herefordshire, unseating the sitting Conservative MP Sir James Rankin.
In parliament he was an advocate of the abolition of the House of Lords.
He was defeated at the January 1910 election by the Conservative candidate Sir James Rankin, who he had ousted. This was despite polling more votes than when he had won in 1906. He did not contest the December 1910 general election or the Leominster by-election in 1912 when no Liberal stood. Leominster Liberals wanted him to run in 1912 but he declined. He retained involvement with the local Liberal association, being elected as its President.
