Armani Williams (born April 14, 2000) is an American professional stock car racing driver who last competed part-time in the NASCAR Xfinity Series, driving the No. 6 Ford Mustang for MBM Motorsports, and part-time in the ARCA Menards Series, driving the No. 13 Toyota Camry for MBM Motorsports. He has also competed in the NASCAR Craftsman Truck Series as well as what are now the ARCA Menards Series East and ARCA Menards Series West in the past.
Williams is the first NASCAR driver openly diagnosed on the autism spectrum. He is one of two currently active autistic NASCAR drivers, along with Cody Ware. Over the course of his NASCAR career, Williams' cars have often sported blue paint schemes with the blue autism puzzle pieces to symbolize his diagnosis on the spectrum and to raise awareness. He is also one of five African-American drivers currently competing in NASCAR, along with Cup Series driver Bubba Wallace, Rajah Caruth, Blake Lothian, and Lavar Scott.
