H.R. Pufnstuf is 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 from September 6, 1969 to December 27, 1969. The broadcasts were successful enough that NBC kept it on the Saturday morning schedule until August 1972. The show was shot in Paramount Studios and its opening was shot in Big Bear Lake, California. Reruns of the show aired on ABC Saturday morning from September 2, 1972 to September 8, 1973 and on Sunday mornings in some markets from September 16, 1973 to September 8, 1974. It was syndicated by itself from 1974 to 1978 and in a package with six other Kroft series under the banner Kroft Superstars from 1978 to 1985.

In 2004 and 2007, H.R. Pufnstuf was ranked #22 and #27 on TV Guide's Top Cult Shows Ever.

H.R. Pufnstuf introdujo el escenario del argumento más utilizado por los Kroffts, girando alrededor de un muchacho llamado Jimmy (interpretado por Jack Wild), que incidentalmente se encuentra con la Isla Viva, un lugar mágico donde todo estaba vivo. El alcalde de Isla Viva era un amigable dragón llamado H.R. Pufnstuf, cuya voz fue prestada por la del escritor del programa, Lennie Weinrib. Jimmy había sido atraído con engaños a la isla con su amigo, una flauta parlante llamada Freddie, por un mágico barco que le ofreció tener aventuras a través del mar. El barco era en realidad poseído y controlado por su némesis, una traviesa bruja llamada Witchiepoo, interpretada por Billie Hayes, que paseaba en una escoba con volante llamada Vroom Broom.
