Wilfred Mott is a recurring fictional character in the British science fiction television series Doctor Who, played by Bernard Cribbins. He is the maternal grandfather of the Tenth Doctor's companion Donna Noble, father of recurring character Sylvia Noble and father-in-law of Geoff Noble. He lives with his daughter's family in Chiswick, London.
Wilfred Mott first appears in "Voyage of the Damned" (2007). The Doctor and Astrid meet him shortly after teleporting down to Earth. He mans a newspaper stand and is one of the few people to remain in London over Christmas following the events of "The Christmas Invasion" and "The Runaway Bride".
He is a staunch monarchist. He witnesses the Doctor and Astrid being teleported back to the Titanic. Donna Noble calls him "Gramps".
In the episode "Partners in Crime", Wilfred is revealed to be an amateur astronomer who spends his evenings stargazing with his telescope from an allotment. He has an interest in alien conspiracies, and is somewhat eccentric. He has a good relationship with his granddaughter who appears to join him on these evenings when she wishes to escape her mother's nagging.
Donna asks him to tell her if he ever sees "a little blue box" and vaguely describes the Doctor to him. After Donna joins the Doctor at the end of the episode, they do a fly-by of the allotment in the TARDIS which astonishes Wilfred. Donna waves to him from the TARDIS door and he is elated to see that she is following her desire for adventure.
