Henry Brown Fuller was an American painter of classical and allegorical works.

Fuller was the son of painter George Fuller. He married fellow artist Lucia Fairchild in 1893 and had two children, Charles and Clara. From 1897 onward, he and his family were members of the Cornish Art Colony in Plainfield, New Hampshire.

Fuller suffered from bouts of severe depression, which contributed to the breakup of his marriage in 1905. In 1906, he was elected into the National Academy of Design as an Associate Academician. He left the Cornish Art Colony to live with his mother in Deerfield, Massachusetts, and died in 1934 in New Orleans.
