Yuyushiki (Japanese: ゆゆ式^?) is a Japanese 4-panel manga series written and illustrated by Komata Mikami, which began serialization in Houbunsha's Manga Time Kirara magazine from April 2008. A television anime adaptation by Kinema Citrus aired in Japan between April and June 2013. An original video animation was released on February 22, 2017. The series' name is derived from the term "yuyushiki jitai" (由々しき事態^?, lit. "in a serious situation").

The series follows the daily lives of three high school girls; the intelligent but childish Yuzuko, the kind but airheaded Yukari, and the mature and easily irritated Yui, who are all part of their school's Data Processing Club (情報処理部, Jōhōshori-bu^?). As the girls spend their days having meaningless discussions, they occasionally come up with themes to research while in the clubroom.

The original manga by Komata Mikami began serialization in Houbunsha's Manga Time Kirara magazine from April 2008. Eight tankōbon volumes of the manga were released between March 26, 2009 and June 26, 2016.
