Max Martin is the professional name of Karl Martin Sandberg, a Swedish record producer and songwriter born on 26 February 1971. He came to prominence in the late 1990s with songwriting credits on a run of pop hits, among them Britney Spears's "...Baby One More Time" (1998), the Backstreet Boys' "I Want It That Way" (1999), Celine Dion's "That's the Way It Is" (1999) and NSYNC's "It's Gonna Be Me" (2000).

Wikipedia counts 31 Billboard Hot 100 number-one singles that he has written or co-written, 29 of them produced or co-produced by him, an all-time record for the chart as of June 2026.
