H.R. Pufnstuf was a children's television series produced by Sid and Marty Krofft in the United States. It was the first Krofft live-action, life-size puppet program. The seventeen episodes were originally broadcast September 6, 1969, to September 4, 1971. The broadcasts were successful enough that NBC kept it on the Saturday morning schedule for a full three seasons, until August 1972, when it was canceled. .
