The Syncopation World Tour is the fourth worldwide concert tour by the South Korean girl group I-dle. The tour began on February 21, 2026 in Seoul.
In December 2025, Cube Entertainment announced that I-dle would be embarking on their 4th world tour titled "Syncopation", following their I-dol World Tour that took place in 2024. It began with 2 shows in Seoul's KSPO Dome on February 21 and February 22, before continuing across Asia and Oceania. Talking about the name of the tour, Miyeon said, "I feel like 'Syncopation' is a word that really suits who we are right now. It feels irregular, yet full of life and impossible to predict. To me, it reflects i-dle continuing to grow by embracing a wide range of new challenges with an open and positive mindset."
All tickets for the Taipei Dome concert were sold out upon the general sales release. It will mark the first time a K-pop girl group will perform there.
