Lego Masters is a British reality show in which teams compete to build the best Lego project. During its original run, it was hosted by Melvin Odoom and judged by Lego designer Matthew Ashton and structural engineer Roma Agrawal (series one) and Fran Scott (series two). Lego Masters premiered on Channel 4 on 24 August 2017. After a hiatus of four years, the show came back for a Christmas special on 24 December 2022 hosted by Nish Kumar and judged by Ashton and Amy Corbett from the American version of Lego Masters. The programme is produced by Tuesday's Child. The 2022 Christmas special was filmed in Warsaw, on the set of Poland's Lego Masters, and co-produced by Endemol Shine Polska.

The series has received strong reviews and positive comparisons to The Great British Bake Off.
