Nathan Williams (born 1964) is an American Zydeco accordionist and singer.
Williams grew up in a Creole-speaking home in St. Martinville, Louisiana, the youngest of seven children. Times were hard for the Williams family and Williams lost his father when he was only seven years old. He developed his musical sensibility in his hometown, a place rich in folk tradition, following in the footsteps of his uncle, the Cajun guitarist Harry Hypolite. Nathan eagerly sought out the music of Zydeco originators such as Clifton Chenier. When he was too young to attend a Chenier dance at a St. Martinville club, he hovered by the window-sized fan at the back of the building to hear his idol, only to have the bill of his baseball cap clipped off by the fan when he leaned too close.
