Cookie☆ is the name of a series comprised of disparate fan works (usually voice dramas) primarily focused on Touhou Project. Both the series and it's name originate from the video Marisa and Alice's Cookie Kiss (often referred to as Cookie☆OG for clarity) which was posted to Nico Nico Douga on February 15th, 2010. The voice drama gained infamy for a multitude of reasons, chief among them being the poor vocal performances.

Today, Cookie☆ features an extensive catalogue of videos and characters. The reasons for their inclusions vary greatly, but typically are because they contain similarities to previously included material, share voice actresses/actors with existing characters, or directly parody/reference Cookie☆ in some way.
