Mushishi (Japanese: 蟲師), also known in English as Mushi-Shi: The Movie and Bugmaster, is a 2006 Japanese fantasy film directed by Katsuhiro Otomo, based on the manga of the same name. It stars Joe Odagiri as Ginko, a traveler who dedicates himself to protecting the populace from supernatural creatures called Mushi. Otomo began work on the film in 2005 after declining a jidaigeki project. He was interested in creating a mix of live action and animation and felt the manga gave him an appropriate creative vehicle.

The film debuted at the Venice International Film Festival in 2006 and was screened at several other festivals prior to its theatrical release on March 24, 2007, in Japan. The DVD was released in Japan in 2007, in the United Kingdom in 2008, and in North America in 2009. The film has received a mixed response from film critics. Many praised Odagiri's performance and its visuals but critiqued the plot and mythology as confusing. Mushishi received nominations and awards at film festivals and was among the 100 highest-grossing films of 2007 in Japan.
