Doctor Who and the Silurians is the second serial of the seventh season in the British science fiction television series Doctor Who. It was first broadcast in seven weekly parts on BBC1 from 31 January to 14 March 1970.

The serial is set in an English moorland, the cave system below it, and London. In the serial, the Third Doctor (Jon Pertwee) attempts to broker peace between humanity and the Silurians, an intelligent bipedal race of reptilians that ruled Earth before humans. This effort becomes undone by a xenophobic usurper Silurian, along with gung-ho human soldiers.

The story is the first appearance of the Silurians, for whom the Silurian hypothesis in science is named.
