Frank “Son” Seals (August 13, 1942 – December 20, 2004) was an American electric blues guitarist and singer. In 2009, Seals was inducted into the Blues Hall of Fame.

Seals was born in Osceola, Arkansas, where his father, Jim “Son” Seals, owned a small juke joint, called the Dipsy Doodle Club. He began performing professionally by the age of 13, first as a drummer with Robert Nighthawk and later as a guitarist. At age 16, he began to play at the T-99, a local upper-echelon club, with his brother-in-law Walter “Little Walter” Jefferson. He played there with prominent blues musicians, including Albert King, Rufus Thomas, Bobby Bland, Junior Parker, and Rosco Gordon.
