Kahlil Gibran (`ka-lil jə-ˈbrän) (November 29, 1922 – April 13, 2008), sometimes known as "Kahlil George Gibran" (note the artist’s preferred Americanized spelling of his first name), was a Lebanese American painter and sculptor from Boston, Massachusetts.

 Called a "master of materials", as both artist and restorer, Gibran turned to sculpture in the mid-fifties.
 In 1972, in an effort to separate his identity from his famous relative and namesake, the author of "The Prophet", Gibran Kahlil Gibran, who was cousin both to his father Nicholas Gibran and his mother Rose Gibran, the sculptor co-authored with his wife Jean a biography of the poet entitled "Kahlil Gibran His Life And World".
 Gibran is known for multiple skills, including painting; wood, wax, and stone carving; welding; and instrument making.
