Mitsudomoe (みつどもえ, "Three-Way Struggle") is a Japanese gag manga series by manga artist Norio Sakurai about the adventures of the Marui triplets in sixth grade and their newly hired teacher Satoshi Yabe as he deals with his new class.

In July 2010, the manga was adapted into an anime series that ran for 13 weeks first airing on Chubu-Nippon Broadcasting.

Yabe usually gets pushed around by the girls and, on occasion, abused by the triplets, who constantly try to pair him with the new school nurse, the clumsy Kuriyama Aiko, as well as continuously get him in trouble with their father, who assumes he is a pedophile.

Mitsudomoe was first written and illustrated by Norio Sakurai in tankōbon format, and has been serialized by Akita Shoten in two of their magazines.
