Henry Taylor Lamb, MC, RA (21 June 1883 – 8 October 1960) was an Australian-born British painter. A follower of Augustus John, he was a founder member of the Camden Town Group.
Born in Adelaide, Australia, he was the son of Sir Horace Lamb FRS. He was educated at Manchester Grammar School, Manchester University Medical School and Guy's Hospital in London, and studied painting at La Palette, Paris.
Lamb saw active service in the First World War in the Royal Army Medical Corps, and was awarded the Military Cross.
A World war II official artist, he is noted for his unusual portraits, as examplified by his well-known picture of an elongated Lytton Strachey. He was elected an Associate of the Royal Academy in 1940 and was made a full Member in 1949. He was a Trustee of the National Portrait Gallery from 1942 and of the Tate Gallery 1944-51. His auction record was set at Christie's in London in June 2006 when his 1910 Breton Boy oil on panel fetched £60,000.
He married Lady Pansy Pakenham, daughter of the 5th Earl of Longford, in 1928, and they had a son and two daughters. Lamb died on 8 October 1960 at the Spiro Nursing Home, Salisbury, Wiltshire at the age of 77.
