Luke Smith is a fictional regular character played by Tommy Knight in the British children's science fiction television series The Sarah Jane Adventures, a spin-off of the long-running series Doctor Who. Luke is a regular character in The Sarah Jane Adventures both in television and audio adventures. He has also appeared in three episodes of Doctor Who: the two-parter "The Stolen Earth"/"Journey's End" (2008), and the Tenth Doctor's finale episode "The End of Time, Part Two" (2010).
Within the narrative of the series, Luke is a human archetype, created by alien species the Bane from thousands of DNA samples, who comes to be adopted by the series' heroine, Sarah Jane Smith (Elisabeth Sladen). Luke is something of a child prodigy, showcasing a remarkable degree of genius but also a level of social ineptitude owing to being born in adolescence.
