Rōben (良弁、朗弁、良辨、朗辨) (689–773), also known as Ryōben, was a Japanese Buddhist monk of the Kegon sect, and clerical founder of the Tōdai-ji temple in Nara, Japan. He is popularly known as the "Golden Bell Practitioner" (金鐘行者 Konshō Gyōja).
According to tradition, he was born in Sagami Province, but as a young baby, was snatched by an eagle and dropped off over a pine tree in front of what is now the Nigatsu-dō Hall. Rōben was raised as a monk, and reunited with his mother 30 years later. In one version of the story, Rōben wore an amulet of Kannon Bodhisattva since he was a baby, which his mother recognized when she came to Nara as a pilgrim. Records with the Ministry of Justice in Nara at the time, do record Rōben as having been raised as a monk since infancy, but do not state anything further as to his origins.
In the fifth year of Tenpyō (733), with government approval, Rōben oversaw expansion and construction of Kinshō-ji (金鐘寺) and the massive bronze statue of Vairocana Buddha. In 740, the twelfth year of Tenpyō, an eminent Korean monk named Simsang (新羅) was invited by Rōben to Japan to help establish a new sect based on the Huayan school of thought, which led to the foundation of the Kegon school with permission from Emperor Shōmu.
Rōben later presided over the drawing of the eyes ceremony of the Great Buddha statue at Tōdai-ji in 751.
