Weird but True! is an American educational children's television series created by and starring Charlie Engelman with his sister Kirby Engelman (seasons 1–2) and Carly Ciarrocchi (season 3). It originally aired on National Geographic Kids for two seasons, and moved to Disney+ for its third and final season.

Inspired by the National Geographic book series of the same name, much of its style and heavy use of paper models created by the Engelmans are continued from their earlier National Geographic short video series Nature Boom Time.
