Porter Kilbert (June 10, 1921 – October 23, 1960) was a jazz alto and tenor saxophonist.
In September 1942, he replaced Preston Love as lead alto saxophonist in Nat Towles' band, before going on to spend two years with Benny Carter's band, playing in line-ups including Willard Brown, Curly Russell, Max Roach, Oscar Bradley, Ulysses Livingston, Sonny White, Teddy Brannon, Bumps Myers, Gene Porter, Alton Moore, J.J. Johnson, Shorty Haughton, Claude Dunson, Snooky Young, Freddie Webster, Gerald Wilson, and Jake Porter.
After a brief spell with Roy Eldridge's band, he joined Red Saunders' band in New York in September 1946. The band later took up residency at Chicago's Club DeLisa, and Kilbert would remain with the Saunders band until January 1952, when he left to form his own band.
In December 1946, he was in a line-up led by Coleman Hawkins, recording for Prestige, with Fats Navarro, Milt Jackson, JJ Johnson, Hank Jones, Curley Russell and Max Roach.
