Sir Kingsley William Amis CBE (16 April 1922 – 22 October 1995) was an English novelist, poet, critic and teacher. He wrote more than 20 novels, six volumes of poetry, a memoir, short stories, radio and television scripts, and works of social and literary criticism. He is best known for satirical comedies such as Lucky Jim (1954), One Fat Englishman (1963), Ending Up (1974), Jake's Thing (1978) and The Old Devils (1986).

His biographer Zachary Leader called Amis "the finest English comic novelist of the second half of the twentieth century." In 2008, The Times ranked him ninth on a list of the 50 greatest British writers since 1945.  He was the father of the novelist Martin Amis.

Amis is widely known as a comic novelist of life in mid- to late-20th-century Britain, but his literary work covered many genres – poetry, essays, criticism, short stories, food and drink, anthologies, and several novels in genres such as science fiction and mystery. His career initially developed in an inverse pattern to that of his close friend Philip Larkin. Before becoming known as a poet, Larkin had published two novels; Amis originally sought to be a poet and turned to novels only after publishing several volumes of verse. He continued throughout his career to write poetry in a straightforward, accessible style that often masks a nuance of thought.

Amis's first novel, Lucky Jim (1954), satirises the highbrow academic set of an unnamed university through the eyes of a struggling young lecturer of history. It was widely perceived as part of the Angry Young Men movement of the 1950s, in reacting against stultification of conventional British life, although Amis never encouraged this interpretation. Amis's other novels of the 1950s and early 1960s likewise depict contemporary situations drawn from his experience.
