J. Will Callahan (March 17, 1874 – November 15, 1946) was an American lyricist known for his contributions to early 20th-century music. Despite being partially blind, Callahan achieved significant success in the music industry. He wrote lyrics for several songs, including "Gasoline" (1913) and "Smiles," which was featured in The Passing Show of 1918. "Smiles" became particularly famous, earning Callahan and composer Lee S. Roberts approximately $500,000. Another notable song by Callahan is the 1917 song "Ching Chong," which is viewed negatively by modern audiences. Callahan frequently collaborated with Max Kortlander throughout his career. His legacy was further celebrated in the book "The Songs of J. Will Callahan, Tin Pan Alley's Blind Lyricist" by Mary Jane Doerr, which won a State History Award in 2022.
