Lowell Fulson (March 31, 1921 – March 7, 1999) was an American blues guitarist and songwriter, in the West Coast blues tradition. He also recorded for contractual reasons as Lowell Fullsom and Lowell Fulsom. After T-Bone Walker, he was the most important figure in West Coast blues in the 1940s and 1950s.

Fulson was born on a Choctaw reservation in Atoka, Oklahoma, to Mamie and Martin Fulson. He stated that he was of Cherokee ancestry through his father but also claimed Choctaw ancestry. His father was killed when Lowell was a child, and a few years later, he moved with his mother and brothers to live in Clarita and attended school at Coalgate.
