The Southern Union Gas Company Building is a historic building in downtown Albuquerque, New Mexico, which is notable as one of the earliest International style buildings in the city. Built in 1951, it was the largest of several Southern Union offices around the state designed by southwestern architect John Gaw Meem. Meem was much better known for working in the Pueblo Revival style but did design a handful of other modernist buildings, such as the Colorado Springs Fine Arts Center.
