TT Zero is an electric motorsport event introduced for the 2010 Isle of Man TT races – replaced the similar TTXGP race as a 1-lap circuit of the Snaefell Mountain Course. The TT Zero event as an officially sanctioned Isle of Man TT race is for racing motorcycles where "The technical concept is for motorcycles to be powered without the use of carbon based fuels and have zero toxic/noxious emissions." The Isle of Man Government offered a prize of £10,000 for the first entrant to exceed the prestigious 100 mph average speed around the Mountain Course.

The 2010 Isle of Man TT Festival was held between Saturday 29 May and Friday 11 June on the 37.73-mile Isle of Man TT Mountain Course. The 2010 races again included a second 600 cc Supersport Junior TT race. The Lightweight TT and Ultra-Lightweight TT race class previously held on the 4.25-mile (6.84 km) Billown Circuit in the Isle of Man for the 2008 Isle of Man TT and 2009 Isle of Man TT were dropped from the 2010 race schedule. The 2010 Isle of Man TT Races included the one-lap TT Zero for racing motorcycles "to be powered without the use of carbon based fuels and have zero toxic/noxious emissions." which replaced the TTXGP and also a Suzuki 50th Anniversary Lap of Honour and the TT Classic Parade which were held before the main Senior TT race.
