Julius Daniels (b. 20 November 1901 in Denmark, South Carolina; d. 18 October 1947)) was an American blues musician. His song "99 Year Blues" appeared on the box set Anthology of American Folk Music and has been covered by Jim Kweskin, Chris Smither, Johnny Winter, Charlie Parr and Hot Tuna on their album Burgers. It has been often credited as a possible source for the tune "Viola Lee Blues", recorded by Cannon's Jug Stompers in the 1920s and the Grateful Dead in 1966.

Although he only recorded a few tunes, Daniels plays an important role in the history of Piedmont blues. One of the first black artists to record in the Southeast, Daniels inspired future bluesmen with his mix of finger-picked blues, sacred and country music.

Recording for the first time, in 1927, Daniels was accompanied by the guitarist Bubba Lee Torrence, with whom he shared billing. During his second recording session, Daniels was joined by the guitarist Wilbert Andrews.

Daniels lived in Pineville, in Berkeley County, between 1912 and 1930. Relocating to Charlotte, North Carolina in 1930, he lived the rest of his life there, working in a variety of jobs, including as a firefighter.
