Lyle Stephanovic (August 19, 1908 – August 5, 2005), better known as Spud Murphy, was an American jazz multi-instrumentalist, bandleader, and arranger.

Born Miko Stefanovic to Serbian émigré parents in Berlin, Germany, Murphy grew up in Salt Lake City, Utah, where he took the name of a childhood friend. Murphy studied clarinet and saxophone when young and took trumpet lessons from Red Nichols's father. He worked with Jimmy Joy in 1927-28 and with Ross Gorman and Slim Lamar (on oboe) in 1928. He worked in the early 1930s as saxophonist-arranger for Austin Wylie, Jan Garber, Mal Hallett, and Joe Haymes, then became a staff arranger for Benny Goodman from 1935 to 1937. At the same time he also contributed charts to the Casa Loma Orchestra, Isham Jones, Les Brown and many others.
