2015 Isle of Man TT

The 2015 Isle of Man TT was held between 30 May and 12 June 2015, on the Isle of Man TT Mountain Course.

Ian Hutchinson took 3 wins in the event, more than anyone that year.

The Senior TT was red-flagged due to the career-ending accident of Jamie Hamilton. John McGuinness won the re-started race, his 23rd, and, as of 2023, last victory at the Isle of Man TT.

The event was marred by the death of 32 year-old French rider Franck Petricola during qualifying.
