The Hells Angels Motorcycle Club (HAMC) is a worldwide one-percenter motorcycle club whose members typically ride Harley-Davidson motorcycles.

In May 2019, a court in Utrecht issued a verdict that made the Netherlands the first country to completely ban the Hells Angels; other countries such as Germany had banned local chapters, but never before the entire club.The United States Department of Justice considers the club to be an organized crime syndicate. In the United States and Canada, the Hells Angels are incorporated as the Hells Angels Motorcycle Corporation. Common nicknames for the club are the "H.A.", "Red & White", "HAMC", and "81".
