The men's 110 metres hurdles at the 2017 World Championships in Athletics was held at the London Olympic Stadium on .

Summary Russian defending champion Sergey Shubenkov, having missed the Olympics due to the drugs scandal, was competing as an Authorised Neutral Athlete. Since the last World Championships, Omar McLeod (Jamaica) had won the Indoor World title and the Olympics and had the year's fastest time. The returning silver medallist was his countryman Hansle Parchment, while the returning bronze medalist was world record holder Aries Merritt (United States), who underwent a kidney transplant four days after the previous championships.

In the final, from the gun, McLeod had a slight lead over the first hurdle and retained the lead throughout. Shubenkov looked to be the only athlete gaining on him from behind. Balázs Baji (Hungary) was close over the first hurdle, but after hitting the second hurdle fell back to sixth before recovering to take the bronze.
