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 is 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 136.358mph (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,^[1] together with the COVID-19 pandemic, the future of the meeting has been called into question.^[2]
