天理教是原属日本教派神道系统、后自立成教的日本新兴宗教之一。江户时代末，1838年由农妇中山美伎在日本大和国山边郡庄屋敷村（今奈良县天理市）创立，信仰父母神“天理王命”（てんりおうのみこと），主要教义认为，父母神创造世界和人类，人的身体是向父母神借来的，必须按照神的意愿支配，通过奉行“圣舞”和拜领“神授”，涤除“灰尘”，净化心灵，愉快地将日常劳作视为“圣劳”，从所有的因缘中了悟天理，最终实现父母神佑护的“康乐生活世界”。天理教的基本经典是被称为“三原典”的《御神乐歌》(圣舞时的歌词)、《御笔先》(记“神示”的1711首和歌，与前书同出自中山美伎之手)和《御指图》(中山美伎和另一领导者饭降伊藏的言论集，被视为“启示录”)，以及为适应战后新情况而由天理教总部于1949年编定的《天理教教典》(1956年译成中文)。

Tenrikyo(天理教,Tenrikyō), sometimes rendered as Tenriism, is a monotheistic, Shinto-derived new religion originating from the teachings of a 19th-century Japanese woman named Nakayama Miki, known to her followers as Oyasama. Followers of Tenrikyo believe that God, known by several names including Tenri-Ō-no-Mikoto, expressed the divine will through Nakayama's role 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.
