Architects & Engineers for 9/11 Truth (AE911Truth) is an American non-profit organization of architects, engineers, and demolition experts who dispute the results of official investigations into the September 11 attacks, including the 9/11 Commission Report. It supports the conspiracy theory that the World Trade Center was destroyed by explosive demolition.

Founded in 2006, the group demands that the United States Congress pursue "a truly independent investigation" into the September 11 attacks as they believe government agency investigations into the collapse of the World Trade Center have not addressed what it calls "massive evidence for explosive demolition." Though as of September 2013, the group's petition to Congress was signed by over 2000 architectural and engineering professionals, the scientific and engineering community has generally rejected the position taken by the group, and several NIST-independent analyses published in peer-reviewed scientific journals provide evidence arguing against the "blast hypothesis".
