Hot Dog was a Saturday morning documentary series for children, seen on NBC from September 12, 1970 to September 4, 1971. Created by Frank Buxton and co-produced by Buxton and Lee Mendelson, the program was notable for its hosts – comedienne Jo Anne Worley, comedian Jonathan Winters and writer and actor Woody Allen. The pilot, televised on March 28, 1970, starred Worley, Allen and Tom Smothers, who was replaced with Winters when the show became a series.

Based on Buxton's travels as a comedian (and later, as host of the ABC series Discovery), which took him on tours to various factories, Hot Dog explained, in a humorous manner, how we do things (such as snore) and how things were made (such as the eponymous hot dogs and their buns, plus condiments like mustard).

Seventy topics were covered during the course of this series, which lasted 13 episodes and was rerun the rest of the season. NBC won a Peabody Award for the series in 1970.Some of the music in this series was performed by The Youngbloods.
