Leroy Carr (March 27, 1905 – April 29, 1935) was an American blues singer, songwriter and pianist who developed a laid-back, crooning technique and whose popularity and style influenced such artists as Nat King Cole and Ray Charles. He first became famous for "How Long, How Long Blues" on Vocalion Records in 1928.

Carr was a native of Nashville, Tennessee, born on March 27, 1905. The family lived on the city's north side, not far from Fisk University, and his father John Carr worked as a porter at nearby Vanderbilt University. Accounts of Carr's early life disagree with one another in many respects, but at some point after his parents separated he left Nashville with his mother for Louisville, Kentucky, and then for Indianapolis, Indiana, a growing city that was a center for automobile-industry jobs until Henry Ford's innovations shifted the focus of black migration to Detroit, Michigan. Carr taught himself to play the piano. He may have dropped out of high school, but he had more formal education than most country blues players of the same time.
