Ài Tóng 愛同 (also Shì Ài-tóng 釋愛同, fl. early Tang) was a Vinaya specialist who is recorded in Zànníng’s 贊寧 Sòng gāosēng zhuàn 宋高僧傳 (T50n2061, j. 14) as a transmitter of the Mahīśāsaka tradition. His principal extant work is the Míshāsāi jié-mó-běn 彌沙塞羯磨本 (KR6k0005), the karmavācanā extract from the Wǔfēn lǜ (KR6k0001) reformatted as a one-fascicle handbook for the conduct of monastic legal acts. The compilation is dated to the 7th century on the basis of his entry in the Sòng gāosēng zhuàn.
