JPMorgan Chase Tower, formerly Texas Commerce Tower, is a 305.41 m (1,002.0 ft), 75-story skyscraper at 600 Travis Street in Downtown Houston, Texas. It is currently the tallest building in the city, the tallest building in Texas, the tallest five-sided building in the world, the 13th tallest building in the United States, and the 79th tallest building in the world.

The tower was built between 1979 and 1981 as the Texas Commerce Tower. It was designed by noted architects I. M. Pei & Partners. In some early plans, the building reached up to 80 stories; however, the FAA expressed concerns that additional height was a risk for aircraft going into and out of nearby William P. Hobby Airport. Nonetheless, when it was completed, it was the eighth tallest building in the world. The building was developed as part of a partnership between Texas Commerce Bank and Khalid bin Mahfouz. It was built on the site where the Uptown Theatre, demolished in 1965, once stood.

Upon its completion, the building surpassed Aon Center in Los Angeles to become the tallest building in the United States west of the Mississippi River, a title it held until Los Angeles's Library Tower, now known as the U.S. Bank Tower, was built in 1990.

JPMorgan Chase Tower is also connected to the Houston Downtown Tunnel System. This system forms a network of subterranean, climate-controlled, pedestrian walkways that link twenty-five full city blocks. The lobby of JPMorgan Chase Tower has been designed to harmonize not only with the height of the structure but also with the portico of Jones Hall, home of the Houston Symphony Orchestra, and which occupies the city block immediately to the west. For that reason, a five-story glass wall supported by a stainless steel space frame spans the entire 85 foot width of the front entrance, making the lobby area light and airy, and opening up the space to the plaza outside.[citation needed]. The Tower also includes 22,000 square feet of retail space. The sky lobby observation deck is located on the 60th floor. The sky lobby acts as a transfer point for persons traveling to the upper (61-75) floors, but also as an observation deck for the public during the working hours of 8:00 a.m. — 5:00 p.m. Monday–Friday, free of charge. One can take the express elevator, providing a panoramic view of the city of Houston thanks to the use of wide glass spans and thirteen-foot ceilings. In the large plaza area at the entrance of the building is a multi-colored sculpture entitled "Personage with Birds", which was designed by painter and sculptor Joan Miró, and which was installed in the plaza in early 1982.

While the tower's name reflects the bank JPMorgan Chase, the only space designated to Chase is a single branch office on the bottom floor. The tower is owned by Prime Asset Management and managed by its original owner, Hines Interests.
