Isaac Walton Taber (c. 1857 – February 12, 1933) was an American illustrator active in the late 19th and early 20th centuries. He was also known as "Walton Taber." As his work was often credited to "I. W. Taber," he has been confused with the photographer Isaiah West Taber (1830-1912). Taber's illustrations were published in magazines including St. Nicholas and Century. Tabor illustrated Rudyard Kipling's Captains Courageous, Frank T. Bullen's Cruise of the Cachalot, and the 1928 edition of Herman Melville's Moby Dick. Taber died in New York City on February 12, 1933.
