PythagoraSwitch (ピタゴラスイッチ, Pitagora Suitchi) is a 15-minute Japanese educational television program that has been aired by NHK since April 9, 2002. It encourages augmenting children's "way of thinking" under the supervision of Masahiko Satō (佐藤雅彦) and Masumi Uchino (内野真澄). A five-minute format called PythagoraSwitch Mini is also available.

During the beginning and ending of each episode, and between each corner (segment), there are Pythagorean Devices (ピタゴラ装置, Pitagora Sōchi). "Pythagorean device" is the equivalent Japanese colloquialism for the American "Rube Goldberg machine" and British "Heath Robinson" contraption. The main focus of the program is a puppet show, but the subject is mainly advanced by small corners. World phenomena, principles, characteristics, and the like are introduced in an entertaining way. At the end of each segment, the show's title is sung as a kind of punchline.
