Anadarko Tower, Postmodern skyscraper in The Woodlands, Texas

Allison Tower, formerly known as Anadarko Tower, is a 32-story glass and steel skyscraper standing 439 feet (134 meters) tall in The Woodlands business district. The building provides around 807,000 square feet (75,000 square meters) of office space served by 18 elevators.

Allison Tower was designed by the firm Gensler and developed by Patrinely Group, with Marek Brothers Systems working to a 12-month construction deadline. It was renamed Allison Tower in a Summer 2013 topping-off ceremony for Robert Allison, Jr., the first CEO of Anadarko Petroleum; the adjacent tower was dedicated to former CEO James Hackett as Hackett Tower.

The tower was renamed Allison Tower during a "Topping Off" ceremony in the summer of 2013, honouring Robert Allison Jr., the first CEO of Anadarko Petroleum. The adjacent tower unveiled at the same event was named Hackett Tower after James Hackett, another former CEO of the company.

Allison Tower stands in The Woodlands, Texas, the tallest building in Montgomery County and the tallest between Houston and Dallas. It is an office building occupied by Occidental Petroleum and owned by Howard Hughes Holdings, so interior access is for tenants and their guests rather than the general public.

The building earned LEED certification, which recognizes its environmental performance and sustainable design standards. This achievement shows how modern commercial construction in the region incorporates responsibility toward the environment.
