Julian Clifton "Matty" Matlock (April 27, 1907 – June 14, 1978) was an American Dixieland jazz clarinettist, saxophonist and arranger.

Matlock was born in Paducah, Kentucky, April 27, 1907, and raised in Nashville beginning in 1917.

[1] From 1929 to 1934, Matlock replaced Benny Goodman in the Ben Pollack band doing arrangements and performing on clarinet.

[2] Matlock's entry in The Rough Guide to Jazz says of him (in part): "Matty Matlock was, with Irving Fazola, the most inspired and spontaneous clarinettist in the Dixieland style, and as a truly original arranger he perfected the sound of 'arranged white Dixieland' as we know it today.

[1] In 1955, he appeared in the film Pete Kelly's Blues, playing clarinet for a band that is seen in a scene in a Kansas City speakeasy in 1927.
