Robert Martin "Bob" Enevoldsen (11 September 1920 Montana – 19 November 2005 Woodland Hills, California) was a West Coast jazz tenor saxophonist and valve trombonist born in Billings, Montana, probably best known for his work with Marty Paich. He also did sessions with Art Pepper and Shorty Rogers, and later extensively played with Shelley Manne. It is a little known fact that Enevoldsen was a highly skilled arranger and did most of the arranging work for Steve Allen's Westinghouse show in the early 60's. During the 1970s he gigged sometimes with Gerry Mulligan also, among others.
