Milton J. "Milt" Franklyn (September 16, 1897 – April 24, 1962) was a musical composer and arranger who worked on the Warner Bros. Looney Tunes animated cartoons.

Franklyn moved from New York to Salt Lake City at the age of three, where he went to high school and finished one year at the University of Utah. He was the state junior tennis champion in Utah for six years. The next two years were spent at the University of California, Berkeley, then he began a term at Pennsylvania University when he was called to service in World War One. Franklyn did not serve overseas; he trained as a naval officer for three months and then the Armistice was signed on November 11, 1918. He returned to Berkeley to finish his education. As Franklyn could play a number of instruments, he joined a band in San Francisco and for the next few years played at the Palace and St. Francis hotels. He began his own nine-piece orchestra, known at various times as the Peninsula Band, the Super Soloists, and the Merrimakers, and appeared in San Mateo (1926 to June 1927), where he also owned a music store, and San Jose (1928 to January 1929), where he was Master of Ceremonies and wrote revues for the California Theatre before moving on to Fresno and Oakland. For two years he was emcee with Fanchon and Marco at Fox West Coast in San Diego; musical director and emcee with Paramount Publix Corporation, travelling to Seattle, Denver, Houston and Toledo; and finally worked on the Loew's circuit in Providence, Rhode Island and New York City from 1933 to 1935. Franklyn quit vaudeville to go to Hollywood in 1935 and spent a year doing occasional work.
