Eiichi Moriwaki

 was a Japanese photographer.
Almost nothing about Moriwaki is known. In the 1930s he was a member of the Osaka Camera Group ( "Ōsaka Kamera Gurūpu") of Kiyoshi Koishi, and in the late thirties a member of Rōka Photography Club ( "Rōka Shashin Kurabu").
The Tokyo Metropolitan Museum of Photography holds works by Moriwaki in its permanent collection.
