101 Marietta Street, formerly Centennial Tower, is a 140 m (460 ft), 36-story skyscraper in downtown Atlanta, Georgia. The building was completed in 1975 and renovated in 1998, resulting in a name change, new facade, and chevrons added to the building which increased its original 136 m (446 ft) height by 4 m (13 ft). The property is considered a class "A" office building consisting of 600,000 square feet.

The U.S. Census Bureau has its Atlanta regional office in Centennial Tower.

Centennial Tower can also be seen in S1E1 of the hit T.V. show The Walking Dead, when Rick sees the reflection of a helicopter passing the tank.[1]
