William Elliott Whitmore (born May 11, 1978, Iowa, United States) is an American blues singer and musician from Lee County, Iowa.

He has recorded a number of albums released on Southern Records, and now is a member of the Anti Records family. His act consists mostly of playing the banjo or guitar while singing, though on occasion he performs a cappella. While he has earned much acclaim from the folk, blues and alt-country communities, he is also rooted in the hardcore punk community, by paying, for example, a homage for the worldwide spread icon of Bad Religion.
