Hugh Peter Martin Donnelly (born in Belfast, 26 March 1964), is a former motor racing driver from Northern Ireland. After promising runs at Formula 3 and Formula 3000, in which he won 3 races and was a championship contender, Donnelly stepped up to F1 with Arrows in 1989.

In 1990 he continued in F1 with Lotus, but after a season of no points, but very promising performances, he suffered a terrible crash during qualifying at the Jerez circuit that crippled him for life. He sustained multiple injuries in the shunt, where he was actually ejected from his car, with his seat still attached to his back. Many onlookers feared the worst but thankfully he recovered, although his F1 career was over.

Donnelly has since managed to race in smaller club events, and manage a Formula Vauxhall team.

Donnelly's involvement in club racing ended in 2004 when he filed for bankruptcy due to failure to pay taxes and legal disputes regarding driver contracts.

In 2004, Donnelly raced a Mazda RX-8 in a Britsports 24hr race at Silverstone and finished in 27th place. 2006 saw Donnelly return to Lotus, participating a track day sponsored by a Lotus owner's club.
