Total Drama World Tour (often shortened as TDWT and formerly titled Total Drama, the Musical) is the third season of the Total Drama series. The series' extension was commissioned by Teletoon from the producers, Fresh TV. The season's elements and plot structure is largely based on The Amazing Race, with the semi-final episode being a direct parody of the reality series.

In this season, fifteen returning contestants and two (later three) new contestants are taken on a trip around the world, and compete in cultural themed challenges of countries they visit. An added twist in this season is that they are required to break spontaneously into song, or else be immediately eliminated. The original cast from this and past seasons do not compete in the next season, Total Drama: Revenge of the Island, as there is a new cast. However, nine of these original contestants each have a cameo in the next season, while seven of them return to compete again in the fifth season, Total Drama All-Stars.

A spin-off series based on this season, The Ridonculous Race, premiered in September 2015.
