WordGirl is an American animated superhero children's television series produced by the Soup2Nuts animation unit of Scholastic Entertainment for PBS Kids. The series began as a series of shorts entitled The Amazing Colossal Adventures of WordGirl that premiered on PBS Kids Go! on November 10, 2006, usually shown at the end of Maya & Miguel; the segment was then spun off into a new thirty-minute episodic series that premiered on September 3, 2007 to August 7, 2015 on most PBS member stations. The series of shorts consisted of thirty episodes, with 128 episodes in the full half-hour series and a film. WordGirl creator Dorothea Gillim felt that most children's animation "underestimated [children's] sense of humor" and hoped to create a more intellectual show for young audiences.

By June 2014, many PBS stations had stopped airing WordGirl, opting to air more popular series throughout the summer. However, new episodes continued to air on select stations, with streaming options on the PBS Kids website and video app. The series ended with the two-part episode "Rhyme and Reason", which was released on August 7, 2015.

The show was created for children ages 4–9. By 2022, the show had gained a cult following through social media.
