Daiyuzenji is a Rinzai Zen Buddhist temple located on the North Side of Chicago, Illinois, in the United States.
Fumio Toyoda, a lay Zen master and martial arts teacher who had emigrated to Chicago from Japan in 1974, was the driving force behind the founding and administration of the betsuin.
Eventually the Chicago betsuin developed a cadre of senior students, including several ordained priests.
In 2005 it was designated a fully independent temple by Hosokawa Roshi, named Sokeizan Daiyuzenji (曹渓山大雄禅寺).
Daiyuzenji teachers and community members were involved with the establishment of Korinji, a new Rinzai Zen Buddhist sodo (monastery) in the Madison, Wisconsin area.
