Richard Allen (Blue) Mitchell (March 13, 1930 – May 21, 1979) was an American jazz, rhythm and blues, soul, rock, and funk trumpeter, known for many albums recorded as leader and sideman on Blue Note Records.

Mitchell was born and raised in Miami, Florida. He began playing trumpet in high school where he acquired his nickname, Blue.

After returning to Miami he was noticed by Cannonball Adderley, with whom he recorded for Riverside Records in New York in 1958. He then joined the Horace Silver Quintet playing with tenor Junior Cook, bassist Gene Taylor and drummer Roy Brooks. Mitchell stayed with Silver's group until the band's break-up in 1964. After the Silver quintet disbanded, Mitchell formed a group employing members from the Silver quintet substituting the young pianist Chick Corea for Silver and replacing a then sick Brooks with drummer Al Foster. This group produced a number of records for Blue Note disbanding in 1969, after which Mitchell joined and toured with Ray Charles till 1971. From 1971 to 1973 Mitchell performed with John Mayall on Jazz Blues Fusion. From the mid – 70s he recorded, and worked as a session man in the genres noted previously, performed with the big band leaders Louie Bellson, Bill Holman and Bill Berry and was principal soloist for Tony Bennett and Lena Horne.
