Shinichi Watanabe (渡邊 慎一, Watanabe Shin'ichi; born September 6, 1964) is a Japanese anime director and voice actor. He is best known for his over-the-top adaptation of Rikdo Koshi's Excel Saga, in which he appears as the character Nabeshin.

Watanabe stated that the nickname Nabeshin (a name blending of "nabe" in Watanabe and "shin" in Shinichi) came to him from God.

About his unique appearance (dressing similar to the character Lupin III) Watanabe said he grew out his afro and started wearing bright clothing in order to stand out and get attention.
