AJ Roach (born 1975) is an American singer-songwriter originally from Virginia, but now based in Ennis, Co. Clare, Ireland. Roach was born in Newport News, Virginia, but his family moved to his parents ancestral home in Duffield, Virginia when Roach was still very young.

As a teenager, Roach reportedly spent a number of months under the tutelage of cult blues guitarist Washboard Williams; however this rumor has never been properly substantiated, and Roach's playing style does not suggest such tutelage.

After attending college in Virginia, Roach lived in several different cities on the east coast of the United States before moving to San Francisco. The move to San Francisco was a turning point for Roach's musical career. There he met and befriended musicians like Tom Meshishnik, Todd Sickafoose, Sean Hayes and Noe Venable. The musical impact that these relationships had on Roach can be heard on Dogwood Winter, his first studio album. The album was jointly produced by Meshishnik and Sickafoose, and features Venable on backing vocals on several tracks.
