Lamb Chop is a sock puppet anthropomorphic sheep created by puppeteer and ventriloquist Shari Lewis. The character first appeared during Lewis' guest appearance on Captain Kangaroo in March 1956 and later appeared on Hi Mom (1957–1959), a local morning show that aired on WRCA-TV in New York, New York.

A sock puppet, sockpuppet, sock-puppet, or sock poppet is a puppet made from a sock or a similar garment. The puppeteer wears the sock on a hand and lower arm as if it were a glove, with the puppet's mouth being formed by the region between the sock's heel and toe, and the puppeteer's thumb acting as the jaw. The arrangement of the fingers forms the shape of a mouth, which is sometimes padded with a hard piece of felt, often with a tongue glued inside.
