Titian Ramsay Peale (November 2, 1799 – March 13, 1885) was a noted American artist, naturalist, entomologist and photographer. He was the sixteenth child and youngest son of noted American naturalist Charles Willson Peale. He is sometimes referred to as Titian Ramsey Peale II to distinguish him from his older brother with the same name who was a favorite of their father and who died at age 18 in 1798.
