Lester J. Kinsey Jr., (March 18, 1927 – April 3, 2001) known as Big Daddy Kinsey, was an American Chicago blues singer, guitarist and harmonica player.

He was born near Pleasant Grove, Mississippi. He grew up playing gospel music; his father was a pastor in the Church of God in Christ and disapproved of blues music. However, Kinsey started playing guitar at parties in Mississippi, before moving in 1944 to Gary, Indiana, where he worked in a steel mill. He married and served in the military before returning to work in Gary and raising a family.
