The Ultra-Lightweight TT is a motorcycle road race that takes place during the Isle of Man TT festival, an annual event at the end of May and beginning of June. Between 1951 and 1974 this race was part of the Grand Prix motorcycle racing season at world-level, representing the British round. The Ultra-Lightweight TT and the Lightweight TT races were both dropped from the 2005 Isle of Man TT race calendar due to lack of entries, but were later reinstated to the 2008 TT race schedule to be held on the 4.25 mi (6.84 km) Billown Circuit.[1]

The Ultra-Lightweight TT race was re-introduced for the 1951 Isle of Man TT race for motorcycles not exceeding 125 cc engine capacity until dropped from the TT race meeting in 1974.
