Alpinestars is a safety gear manufacturer for several types of racing (Moto GP, Motocross, Formula 1), as well as extreme sports. They also produce casual mens and womens sportswear lifestyle apparel for motorsports enthusiasts. The company takes its name from the English translation of the Italian word for "edelweiss" (stelle alpine). When translated into English, stelle alpine literally means "Alpine stars".

Founded in 1963 by Sante Mazzarolo in Asolo, Veneto. The company started out making hiking and ski boots, but quickly focused on making boots primarily for motocross racing. In the 1990s, the company branched out into manufacturing all types of protective and technical gear ranging from gloves and jackets to full leather suits. Today they have offices in Los Angeles as well as the original headquarters/factory and main research & development labs remaining in Northern Italy. The company today is headed by Sante's son, Gabriele Mazzarolo.

Their claim to fame is the Tech 8 boots that have been worn on the feet of some of the best motocross and supercross racers. Alpinestars has recently branched out into other sports and now have leather gear for superbike and GP riders, driving shoes and flame retardant gear for race car drivers, as well as casual clothing.
