Martijn Gerard Garritsen (born 14 May 1996), known professionally Martin Garrix (stylized as Mar+in Garri×), is a Dutch DJ, record producer and musician. He is ranked number 1 on DJ Mag's Top 100 DJs list for 2016. In 2016, he founded the label STMPD RCRDS months after leaving Spinnin' Records, before signing with Sony Music. In 2017, he was announced as a resident DJ at Hï Ibiza.

Garrix learned to play guitar at age 8. In 2004, he expressed interest in becoming a DJ after seeing Tiësto perform at the Olympic games in Athens. He took particular inspiration from the track "Traffic", prompting him to download specialist software, FL Studio, and enabling him to start composing. In 2013, he graduated from the Herman Brood Academy, a production school in Utrecht. Garrix ghost writes tracks for other artists, and despite this, only one in fifty of his tracks have made it out to the public. In an interview when asked about his social class, Garrix said middle-class. He also said his 'dream mentor' was Calvin Harris.
