Dave Koz was born on March 27, 1963 is a American jazz saxophonist. He often draws comparisons to another well-known saxophonist, David Sanborn. Because the two sound almost alike, Koz is sometimes billed as "the second coming of Sanborn".

He usually plays soprano and alto saxophones, but sometimes plays tenor and occasionally baritone. In 2002, Koz started a record label, Rendezvous Entertainment, with Frank Cody and Hyman Katz. One of the first albums from that label was Golden Slumbers: A Father's Lullaby, which came at the time his brother Jeff became a father for the first time.

In an April 2004 interview with The Advocate, Koz came out publicily as a gay man. Later the same year, he was named by People magazine as one of their "50 Hottest Bachelors" in their June issue.

In 2004 he recorded the Luther Vandross song "If Only For One Night" with Paul Jackson, Jr., Brian Culbertson and Lenny Castro, as one of the tracks for the GRP Records tribute album, Forever, For Always, For Luther.

In 2006, he played on all the songs for the followup tribute album, released this time on his own Rendezvous Entertainment label, called Forever, For Always, For Luther Volume II, which also was produced by Rex Rideout and Bud Harner. Vandross also appeared as a background vocalist on the single "Can't Let You Go (The Sha-La Song)" from Koz's 1999 album, The Dance.

In 2006, Koz was selected to host a syndicated afternoon show for Broadcast Architecture's new Smooth Jazz Network. The show, based in Los Angeles, is broadcast on other Smooth Jazz stations across the country. Koz and Ramsey Lewis are the only two Smooth Jazz personalities to host two different syndicated shows during the week.
