Danny Dyer (born Danial John Dyer; 24 July 1977) is an English actor and presenter. Dyer's breakthrough role was as Moff in Human Traffic (1999), with other notable roles Billy the Limpet in Mean Machine (2001) and as Tommy Johnson in The Football Factory (2004). Following the success of The Football Factory, Dyer was often typecast in "hard-man" roles, although it was this image that allowed him to present The Real Football Factories, its spin-off, The Real Football Factories International and Danny Dyer's Deadliest Men. Dyer has also worked in theatre, having appeared in three plays written by Harold Pinter, with whom he had a close friendship.

In 2013, Dyer joined the cast of the BBC soap opera EastEnders, in the role of Mick Carter. He had previously turned down a role in 2009 and, in his 2010 autobiography Straight Up, said he would not join the cast until he was "fat, bald and fifty". He won the Serial Drama Performance award at the National Television Awards in 2015, 2016, and 2019. From 2019 until 2022, he presented the BBC game show The Wall.
