The No Sleep Festival is an annual electronic music festival held in Belgrade, Serbia. It originated from the "No Sleep Novi Sad" stage at the EXIT Festival, eventually developing into a standalone event organized by the EXIT team. The festival typically takes place over a weekend in November and is characterized by a multi-day, 24-hour continuous music program across various venues in the Serbian capital.
The event focuses primarily on electronic subgenres such as techno, house, and experimental music. Its central location is often the Port of Belgrade (Hangar), supplemented by performances in established Belgrade nightclubs like Drugstore and 20/44. In addition to musical performances, the festival has historically included daytime programming such as workshops and exhibitions under the "No Sleep Conference" banner, covering topics related to the music industry and club culture.
In 2019, the No Sleep Festival received international recognition at the European Festival Awards, where it was named the "Best New Festival." The event serves as a platform for both internationally recognized DJs and local performers within the European electronic music circuit.
