"Midnight" is the tenth episode of the fourth series of the British science fiction television series Doctor Who. It was first broadcast on BBC One on 14 June 2008.

Donna Noble is a fictional character in the long-running British science fiction television series Doctor Who. Portrayed by British actress and comedian Catherine Tate, she is a companion of the Tenth and Fourteenth Doctors. Originally appearing in the closing scene of the show's 2006 series and as a special guest star in its following Christmas special, "The Runaway Bride", Tate was not expected to reprise her role as Donna; for series 3 (2007), the Doctor travelled alongside medical student Martha Jones. However, Tate expressed interest in returning to the role, and returned as a series regular in series 4 (2008), the subsequent 2009–2010 Christmas and New Year's special, and in the 60th anniversary specials in 2023.
