Dash Berlin is a Dutch electronic music group started in 2007 in The Hague by Eelke Kalberg and Sebastiaan Molijn. Dash Berlin were voted the seventh most popular DJs in the world according to DJ Mag in 2012; Kalberg and Molijn were record producers. Kalberg and Molijn left the group in 2019 and returned in 2021 after winning a legal dispute against Jeffrey Sutorius over the "Dash Berlin" trademark. Since 2022 Ryan Fieret is the frontman of the group.

Kalberg and Molijn have been contributing to the international dance scene for over twenty years, with award-winning and platinum-selling hits for dance acts such as Alice Deejay, Vengaboys, Candee Jay, Pronti and Kalmani and Solid Sessions. Their track "Better Off Alone" was one of the first trance records that became big in the U.S. and was later sampled by French superstar DJ David Guetta in his song "Play Hard" and one of America's biggest rappers Wiz Khalifa in his breakthrough record "Say Yeah". They also had worked together with DJ Sander Kleinenberg on classic tracks like "This Is Miami" and "The Fruit" and remixes for major artists such as Justin Timberlake ('Rock Your Body' Remix winning the award for 'Best Remix' at the Dance Star USA Awards), Janet Jackson, BT, Usher, N.E.R.D., Lenny Kravitz, Junkie XL, Röyksopp, Mylo and Annie Lennox.

On 18 June 2018, Sutorius announced his split from Dash Berlin while severing ties with Kalberg and Molijn, alleging mismanagement and career neglect issues. Beginning October 2018, Sutorius has been performing and releasing songs credited under his own name, while Dash Berlin continued as a duo. Sutorius later gained legal ownership of the name on 21 June 2019 while Kalberg and Molijn were forced out from Dash Berlin to pursue their own musical projects.

On 29 March 2021, Sutorius announced on his Facebook page that he would onwards perform, produce and release music under his own name "Jeffrey Sutorius". The announcement came after he had lost a legal dispute with the former members of the group who has since 17 March 2021 been the legal owners of the Dash Berlin trademark.
