Yandere Simulator is an upcoming stealth action video game for Windows. The story follows obsessively lovesick schoolgirl Ayano Aishi, nicknamed "Yandere-chan", who takes it upon herself to eliminate (through either violent or non-violent means) anyone she believes attracting the attention of her "senpai", Taro Yamada. A 1980s-set prequel game mode, Yandere Simulator: 1980s Mode, following the similar story of Ayano’s parents, was soft-launched on October 10, 2021. The non-canon Yandere Simulator: Mission Mode follows Ayano as an assassin pursued by a hunter named Nemesis.

The game began development in 2014 by YandereDev, an American independent game studio led by Alex Mahan, previously known for work as associate designer of the fighting game Girl Fight. It achieved significant of attention online the following year, leading to millions of downloads of pre-release versions of the game, as well as crossovers and spin-offs. Yandere Simulator has also endured a lengthy development and been subject to several controversies.
