The Greatest Dancer is a British dance competition television series created by Simon Cowell and produced by Syco Entertainment. The first BBC programme created by Cowell, The Greatest Dancer sees previously undiscovered dance acts perform live weekly for Cheryl, Oti Mabuse, Matthew Morrison and Todrick Hall (the "Dance Captains") and a studio audience in a competition to win £50,000 and a chance to perform on Strictly Come Dancing.

The first series aired on BBC One on Saturdays from 5 January to 23 February 2019, and was won by 14-year-old solo dancer Ellie Fergusson from Livingston, West Lothian, who was mentored by Oti Mabuse. A second series premiered on 4 January 2020, with the addition of Todrick Hall to the judging panel, and Curtis Pritchard replaced Amelia Wilson as the receptionist. The series ran until 7 March 2020, when it was won by Latin and ballroom dancers Michael and Jowita, also mentored by Mabuse. On 28 April 2020, the BBC announced that were no plans for any further series of The Greatest Dancer.
