WWE Worlds Collide, also known as NXT Worlds Collide, is a professional wrestling event series produced by WWE, an American-based professional wrestling promotion. Established in 2019, the concept is interbrand competition between WWE's various brand divisions. Although the event has been held primarily for WWE's developmental territories, NXT and the former NXT UK, other brands have also been featured. The event was put on hiatus after the 2020 event but returned in 2022. The 2022 event was also the last event for NXT UK as it will be relaunched as NXT Europe in 2023.
