Sammy Going South (retitled A Boy Ten Feet Tall for its later US release) is a 1963 British adventure film directed by Alexander Mackendrick, photographed by Erwin Hillier and starring Edward G. Robinson, Fergus McClelland and Constance Cummings.

Sammy Going South was based on a 1961 novel by W. H. Canaway and adapted for the screen by Denis Cannan. It was produced by Michael Balcon Productions and Bryanston Films. The film had a difficult production period; Robinson suffered a heart attack and some cast members were bitten by snakes. It was first broadcast on British television on BBC2 on Christmas Day 1970 and on American television by the American Broadcasting Company (ABC) in 1971.
