Martin Karl Sandberg, known professionally as Max Martin, is a Swedish music producer and songwriter. He rose to prominence in the mid-1990s after making a string of major hits for artists such as the Backstreet Boys, Britney Spears and NSYNC. Some of his earlier hits include "I Want It That Way" (1999), "...Baby One More Time" (1999) and "It's My Life" (2000).

His trademark during the second half of the 1990s and the early 2000s was a dance-able, keyboard-laden pop sound that blended music styles such as funk and Europop. However, with Kelly Clarkson's songs "Since U Been Gone" (2004) and "Behind These Hazel Eyes" (2005), Martin stepped back into the spotlight after reinventing himself with a heavier, rock-tinged sound.

Since 1999, Martin has written and co-written 21 Billboard Hot 100 number-one hits (most of which he has also produced or co-produced) in the United States, including Katy Perry's "I Kissed a Girl" (2008), Pink's "So What" (2008), Britney Spears's "Hold It Against Me" (2011), Maroon 5's "One More Night" (2012), Taylor Swift's "Shake It Off" (2014). Martin is the songwriter with the third-most number one singles on the chart, behind only Paul McCartney (32) and John Lennon (26).

In 2015, Martin won the ASCAP Songwriter of the Year award for the fifth consecutive year and for the eighth time in his career tying him with Jimmy Jam and Terry Lewis as the top recipient of the award.

As of February 2015 Martin has had a total of 54 songs reach the top ten charts placing him above Madonna's 38, Elvis Presley's 36 and the Beatles' 34.

In 2014 Martin broke ahead of Jimmy Jam and Terry Lewis and Dr. Luke to take the second-place position on the list of most number one hits for a producer behind only George Martin who has 23.

In early 2013 his single sales were tallied by The Hollywood Reporter to be at over 135 million.
