Kiss×sis (Japanese: キス×シス, Hepburn: Kisu×shisu^?) is a Japanese seinen manga written and illustrated by Bow Ditama. It began serialization in Bessatsu Young Magazine (now Young Magazine) on December 11, 2005 and has since been published into fifteen volumes by Kodansha. The manga was later adapted into two animated series by Feel; a twelve-episode television show aired from April 5 to June 21, 2010 by AT-X, and an original video animation series from December 22, 2008 to April 6, 2015.

Keita Suminoe is a third-year Japanese middle school student living with his father, stepmother, and older twin stepsisters, Ako and Riko. Since the remarriage of their parents at childhood, the siblings have always been affectionately close and supportive of one another. Nowadays the trio see their opposites in a noticeably less platonic fashion; Ako and Riko frequently flirt and lust after Keita while, much to his stress, he fights the urge to give in to them.

Kiss×sis began as a series of one-shots in January 2004 by Bow Ditama, an illustrator known for his work on Mahoromatic, published by Kodansha in their now-defunct bimonthly Bessatsu Young Magazine, a manga magazine aimed at a mostly adult male audience.Kiss×sis transferred to Weekly Young Magazine in September 2008, and again transferred to Monthly Young Magazine on December 9, 2009. It had been on a hiatus from the magazine between the August 2013 and January 2014 issues. The first tankōbon volume was released on September 6, 2007 by Kodansha under their KC Deluxe imprint, with 13 volumes released as of August 6, 2014. The manga is also licensed in Taiwan by Sharp Point Press.
