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.

"The Runaway Bride" is a special episode of the long-running British science fiction television programme Doctor Who, starring David Tennant as the Tenth Doctor. It was produced as the Doctor Who Christmas special for 2006, broadcast on 25 December, and aired between the second and third series of the relaunched show.
