Hammel, Green and Abrahamson, commonly called HGA, is an architecture and engineering firm based in Minnesota. It was founded in 1953 by Minnesotans Dick Hammel and Curt Green (Bruce Abrahamson joined in shortly thereafter).

All three of HGA's founders were schooled in the Bauhaus tradition, which stressed an inter-disciplinary approach to Modernism. They began their work designing K-12 school buildings. The firm later expanded into other areas. They are currently one of the largest firms in Minnesota.

HGA has expanded into seven national offices; Los Angeles, Sacramento and San Francisco, CA; Milwaukee, WI; Minneapolis and Rochester, MN; and Washington, D.C.[1]
