Tenrikyo (天理教, Tenrikyō) is a Japanese new religion which is neither strictly monotheistic nor pantheistic, originating from the teachings of a 19th-century woman named Nakayama Miki, known to her followers as "Oyasama". Followers of Tenrikyo believe that God of Origin, God in Truth, known by several names including "Tsukihi," "Tenri-Ō-no-Mikoto" and "Oyagamisama" revealed divine intent through Miki Nakayama as the Shrine of God and to a lesser extent the roles of the Honseki Izo Iburi and other leaders. Tenrikyo's worldly aim is to teach and promote the Joyous Life, which is cultivated through acts of charity and mindfulness called hinokishin.

The primary operations of Tenrikyo today are located at Tenrikyo Church Headquarters, which supports 16,833 locally managed churches in Japan, the construction and maintenance of the oyasato-yakata and various community-focused organisations. It has 1.75 million followers in Japan and is estimated to have over 2 million worldwide.

The ultimate spiritual aim of Tenrikyo is the construction of the Kanrodai, a divinely ordained pillar in an axis mundi called the Jiba, and the correct performance of the Kagura ritual around the Kanrodai, which will bring about the salvation of all human beings. The idea of the Jiba as the origin of earthly creation is called moto-no-ri, or the principle of origin. A pilgrimage to the Jiba is interpreted as a return to one's origin, and is thus also known as "returning to O-Jiba" (おぢば帰り, o-jiba gaeri). As such, the greeting okaeri nasai (お帰りなさい 'welcome home') can be seen at many hotels and guesthouses in Tenri City.

Other key teachings include:

The Joyous Life in Tenrikyo is defined as charity and abstention from greed, selfishness, hatred, anger, covetousness, miserliness, grudge bearing, and arrogance. Negative tendencies are not known as sins in Tenrikyo, but rather as "dust" that can be swept away from the mind through hinokishin (ひのきしん or 日の寄進) and prayer. Hinokishin, voluntary effort, is performed not out of a desire to appear selfless, but out of gratitude for kashimono-karimono and shugo (providence).

One of the most basic teachings of Tenrikyo is kashimono-karimono (貸物借物 or 貸し物借り物), meaning "a thing lent, a thing borrowed". The thing that is lent and borrowed is the human body. Tenrikyo followers think of their minds as things that are under their own control, but their bodies are not completely under their control.

The sacred name of the single God and creator of the entire universe in Tenrikyo is Tenri-Ō-no-Mikoto (天理王命). Tenri-Ō-no-Mikoto created humankind so that humans may live joyously and to partake in that joy. The body is a thing borrowed, but the mind alone is one's own, thus it is commonly accepted that Tenri-Ō-no-Mikoto is not omnipotent.

Other gods are considered instruments, such as the Divine Providences, and were also created by Tenri-Ō-no-Mikoto.
