James Robert Belden (born October 31, 1956) is an American saxophonist, arranger, composer, bandleader and producer. He is noted for his Grammy Award winning jazz orchestral recording titled The Black Dahlia. He is also a past head of A & R for Blue Note Records.

Belden was born in Evanston, Illinois, and raised in South Carolina. In his formative years, Belden studied saxophone with Lou Marini Sr., father of famed jazz saxophonist, Lou Marini (Buddy Rich Big Band, Blood, Sweat and Tears, best known as "Blue Lou" of the Blues Brothers Band). Belden attended the University of North Texas and was a member of the famed One O'Clock Lab Band. While at UNT Belden amassed a huge record collection which included every Blue Note album in existence. He has an encyclopedic knowledge of both the musical and the historical aspects of jazz, in addition to other forms of music such as opera, and contemporary classical music. This has been evident in his work reissuing the music of Miles Davis on Columbia, for which he received Grammy awards. A familiarity with details of recording dates, personnel, and specific takes have proven invaluable in preserving and documenting that period of jazz.
