Nao Deguchi (出口 なお) (January 22, 1837 – November 16, 1918) was a Japanese religious leader who founded the Oomoto religion together with Onisaburo Deguchi. The origins of Oomoto began when she was possessed by a spirit called Ushitora no Konjin in 1892. Even though she was illiterate, she wrote 200,000 pages of prophesies while possessed. While Nao Deguchi is the Foundress (開祖, Kaiso) of Oomoto, Onisaburo Deguchi is the Holy Teacher (聖師, Seishi).
