Chase Tower, Skyscraper in Amarillo, Texas, United States

Chase Tower is a 114-metre, 31-storey office skyscraper in Amarillo, West Texas, the tallest building in the city and the wider region. Its massing closely resembles One Financial Plaza in Fort Lauderdale, Florida, which it exceeds by about three storeys. The tower has carried several names, including SPS Tower, Bank One Center and Amarillo Tower.

The tower was built as the SPS Tower for Southwestern Public Service, the regional electric utility whose offices it housed, and later served as home to the Amarillo branch of American National Bank. It passed through the names Bank One Center and Chase Tower, and in 2006 Chase became the main tenant and gave the building its logo. It was renovated in 2007 and added to the National Register of Historic Places on March 6, 2019.

The tower's name changed with its main tenant: Southwestern Public Service, Bank One, Chase and now FirstBank Southwest. The Amarillo Club, a members-only dining facility, is among the current tenants, alongside the Amarillo Globe-News and Cactus Feeders. The building is often mistaken for One Financial Plaza in Fort Lauderdale, Florida, which it closely resembles.

The tower stands in downtown Amarillo and is best seen from street level, where its 31 stories rise above the surrounding blocks. The building is a working office tower with a bank branch, cafe and fitness center used by tenants, so visitors should plan around weekday business hours. Its top is visible from several blocks away.

The tower closely resembles One Financial Plaza in Fort Lauderdale, Florida, standing only about three stories taller than its counterpart. In October 2008, West Texas A&M University letters were installed on the facade as part of an agreement to host university classes in the building.
