Thomas & Friends: The Great Race is a 2016 British animated musical comedy adventure film and feature-length special of the British television series, Thomas & Friends. The film was produced by HIT Entertainment and animated by Arc Productions.

The film stars the voices of Joseph May and John Hasler as the voice of Thomas in the US and the UK, respectively. It also stars the voices of Rasmus Hardiker, Kerry Shale, Christopher Ragland, Nigel Pilkington, Rob Rackstraw, Teresa Gallagher and Keith Wickham, with Mark Moraghan narrating.Tina Desai, Rufus Jones and John Schwab join the cast, with Jones taking on the role of the iconic real-life locomotive Flying Scotsman, who appeared only in the Railway Series book Enterprising Engines and was reduced to a brief cameo role when the book was adapted for television. In an effort to expand the preschool franchise, the new engines are from locations around the world and include several female characters. The film borrows concepts from the 1991 book Thomas and the Great Railway Show, but is not a direct adaptation of said book.

This was the last production to be animated by Arc Productions under their original name before they were bought by Jam Filled Toronto in August 2016, as well as the last feature-length production from HiT Entertainment before being renamed to Mattel Creations, (later Mattel Television) in March 2016.
