The Ulster Grand Prix is a (currently) defunct motorcycle road race which took place on the 7.401 mi (11.911 km) Dundrod Circuit made up entirely of closed-off public roads near Belfast, Northern Ireland. Due to the races having the fastest average speed over a single lap of any motorcycle road race, it was the fastest race of its kind (Road Racing) in the world. The lap record of 136.415 mph (219.539 km/h) was set by Peter Hickman in the 2019 superbike race, a faster average than the Isle of Man TT lap record, which stands at 136.358 mph (219.446 km/h) as of 2024, set also by Peter Hickman.

The last running of the event occurred in 2019. As a consequence of increased insurance and sundry costs, in association with diminished sponsorship revenue, together with the COVID-19 pandemic, the future of the meeting has been called into question.

However at the Irish Motorbike Awards held on November 3, 2025, an announcement was made that the Ulster Grand Prix would be resurrected, with the provisional date set for the meeting to return as part of the 2027 International Road Racing calendar.
