December 10 are a seven-piece British boyband, currently based in London, United Kingdom. The band formed in 2025 as part of a search for talent directed by their now-mentor Simon Cowell. They were described as an entry to compete against top industry trends, such as the internationally ground breaking k-pop boy bands and girl groups and the rising success of female artists.

The band have recently been signed to Universal Music Group and are currently recording new music that will eventually launch the band’s name into the world as early as 2026.
