The Goodwood Festival of Speed is an annual motorsports festival featuring modern and historic motor racing vehicles taking part in a hillclimb and other events, held in Goodwood House, West Sussex, in late June or early July. The event is scheduled to avoid clashing with the Formula One season, enabling fans to see F1 machines as well as cars and motorbikes from motor racing history.

In the early years of the Festival, which started in 1993, tens of thousands attended over the weekend. As of 2014, it attracted crowds of around 100,000 on each of the three days it was held. A record crowd of 158,000 attended in 2003, before an advance-ticket-only admission policy came into force; attendance was subsequently capped at 150,000.
