Nao Nagasawa (永澤菜教, May 12th, 1971 - present) is a Japanese voice actress. In the 1999 Tottoko Hamutaro Anime Dechu! OVA, she voiced Hamtaro. She was succeeded by Kurumi Mamiya in future media (2000 onward).
She is not to be confused with a separate actress named Neo Nagasawa (born in January 1984), who did not have any Hamtaro roles.
