1stBank Center, Demolished arena site in Broomfield, Colorado, USA

The 1stBank Center was a multi-purpose arena in Broomfield, Colorado, about 15 miles northwest of Downtown Denver, near Rocky Mountain Metropolitan Airport and Flatiron Crossing Mall. It seated up to 6,500 patrons and was designed to give an arena-sized show a theater-like feel. It closed in 2023 and was demolished in 2024.

The venue opened in 2006 as the Broomfield Event Center and was initially built to host sports events for the surrounding area. After redesign work between 2009 and 2010, it reopened with a new focus on concerts and entertainment performances.

The arena stood 15 miles northwest of Downtown Denver, near Rocky Mountain Metropolitan Airport and Flatiron Crossing Mall. After the 2009–2010 renovation, more than 2,000 parking spaces were added and a pedestrian bridge linked the venue to RTD's US 36 and Broomfield Park-n-Ride. The building closed on November 30, 2023, and demolition began in November 2024.

The arena's final event, on September 27, 2023, was an episode of AEW Dynamite; it had hosted the same wrestling show in March 2020. Demolition began in November 2024 at a cost of $3 million, and by May 2025 the site was a dirt lot.
