D-Frag! (Japanese: ディーふらぐ!, Hepburn: Dīfuragu!), also known as D-Fragments, is a comedic manga series by Tomoya Haruno that began serialization in Media Factory's Monthly Comic Alive in July 2008. A 12-episode anime television series adaptation by Brain's Base aired from January 6 to March 24, 2014.

The story focuses on a semi-connected series of sketches as delinquent student Kenji Kazama is forced into joining his school's struggling "Game Creation Club" (Game Development Club in the Seven Seas translation) by its members, a quartet of crazy women with their own eccentricities and self-proclaimed elemental affinities that drive him crazy. As he attempts to distance himself from the club, the more he seems to run into not only his fellow club members, but others from his school who drive him insane to different degrees.
