Lonely Boy is a 1962 Canadian cinéma vérité documentary about the former teen singer Paul Anka.

This short documentary makes use of hand-held cameras to record intimate backstage moments.

It was produced by the National Film Board of Canada and directed by Roman Kroitor and Wolf Koenig.

[1] Lonely Boy was a substantial influence on the Peter Watkins film Privilege.

One scene showing the central character, Steven Shorter, at a table with a venue owner is virtually a one-to-one reproduction of a scene in Lonely Boy, even using the same name (Uncle Julie) for the like-mannered venue owner.
