Billy James Mitchell (born 7 April 2001) is an English professional footballer who plays as a defensive midfielder for club Millwall.
Mitchell hails from Orpington, but moved to Sidcup with his mother and brother when he was 15. He joined his boyhood club Millwall at under-15 level. His father's family originates from Bermondsey and are also Millwall fans, so is his maternal great-grandfather.

In the summer of 2019 he signed his first professional contract, a one-year deal. In April 2021, he signed a new long term deal with Millwall. He scored his first professional goal in a 4âÂÂ1 win against Bristol City on 1 May 2021. Mitchell was awarded the PFA Championship Players in the Community award for the 2021âÂÂ22 season after becoming heavily involved in Millwall's Community Trust.
