Albert Nelson (April 25, 1923 – December 21, 1992), known by his stage name Albert King, was an American guitarist and singer who is often regarded as one of the greatest and most influential blues guitarists of all time. He is perhaps best known for his popular and influential album Born Under a Bad Sign (1967) and its title track. He, B.B. King, and Freddie King, all unrelated, were known as the "Kings of the Blues". The left-handed Albert King was known for his "deep, dramatic sound that was widely imitated by both blues and rock guitarists".

He was once nicknamed "The Velvet Bulldozer" because of his smooth singing and large size – he stood taller than average, with sources reporting 6 ft 4 in (1.93 m) or 6 ft 7 in (2.01 m), and weighed 250 lb (110 kg) – and also because he drove a bulldozer in one of his day jobs early in his career.

King was inducted into the Blues Hall of Fame in 1983. He was posthumously inducted into the Rock and Roll Hall of Fame in 2013. In 2023, he was ranked number 22 on Rolling Stone's 250 Greatest Guitarists of All Time.
