The X Factor: The Band is a special edition of British reality talent competition The X Factor, which premiered on 9 December 2019 on ITV. The format for the series was announced on 4 November 2019 as a last-minute replacement for a planned All Stars spin-off series, which was originally supposed to air following The X Factor: Celebrity in late 2019. The format is an accelerated version of The X Factor whereby solo artists auditioned in front of Simon Cowell and Nicole Scherzinger to try to win a place in a boyband or girlband. The new bands would then compete for a chance to join Cowell's record label and launch their careers.

The X Factor is a British reality television music competition, created by Simon Cowell. Premiering on 4 September 2004, it was produced by Fremantle's British entertainment company, Thames, and Cowell's production company Syco Entertainment for ITV, as well as simulcast on Virgin Media One in Ireland. The programme ran for around 445 episodes across fifteen series, each one primarily broadcast late in the year, until its final episode in December 2018. The majority of episodes were presented by Dermot O'Leary, with some exceptions: the first three series were hosted by Kate Thornton; while Caroline Flack and Olly Murs hosted the show for the twelfth series.
