Underoath Announce Define The Great Line 20th Anniversary Tour for Fall 2026

Underoath are giving one of the defining heavy records of the 2000s the kind of celebration it deserves.

The band has officially announced a Define The Great Line 20th anniversary tour for fall 2026, a commemorative run that will see them bring the landmark album back to stages across North America in some of the biggest headline rooms of their career. For fans looking for more Underoath tour dates and ticket information, Concert Addicts also has additional artist event listings and upcoming show details.

The tour begins November 5, 2026 in St. Louis and will hit cities including Las Vegas, Vancouver, Chicago, Boston, Brooklyn, Atlanta, and more before wrapping up in the band’s hometown of Tampa on December 18, 2026. Support will rotate from longtime friends As Cities Burn, Emery, and select appearances from Atreyu, turning the whole run into something that feels less like a standard anniversary package and more like a shared scene-history celebration.

That feels fitting for an album like Define The Great Line. When it arrived in 2006, it did not just deepen Underoath’s sound, it helped redraw the boundaries of what a heavy record in that space could be. It was darker, more unstable, more atmospheric, and more emotionally volatile than a lot of what was surrounding it at the time. Songs like “Writing On The Walls,” “In Regards To Myself,” and “You’re Ever So Inviting” did not simply hit hard, they felt like they were tearing themselves open in real time. That intensity is a huge part of why the album still holds such a firm place in heavy music memory two decades later.

Chris Dudley’s statement around the tour gets at that legacy well. For Underoath, this is not just about revisiting a successful record. It is about revisiting a body of work that changed their lives, shaped their audience, and gave people language for emotions they had buried deep. Anniversary tours can sometimes feel automatic. This one sounds like it means something to the people on stage too.

Before the fall headline run begins, the band will also spend the summer on the Van Tour To Vans Warped Tour with Held., mixing intimate club dates with Warped Tour appearances and select festival stops. That smaller run makes a nice contrast to what is coming later in the year. One season finds them back in the van, the next puts them in rooms sized for the legacy they have built.

Tickets are available first through an Amex presale beginning June 9, 2026 at 12 PM ET. Artist and additional presales continue through the week, ahead of the general onsale on Friday, June 12, 2026 at 10 AM local time. VIP package information is available through the band’s official site.
