"The Lazarus Experiment" is the sixth episode of the third series of the revived British science fiction television series Doctor Who. It was broadcast on BBC One on 5 May 2007 and stars David Tennant as the Tenth Doctor and Freema Agyeman as Martha Jones.

In the episode, Professor Richard Lazarus (Mark Gatiss) demonstrates an experiment at his laboratory near Southwark Cathedral in Southwark where he renews himself into a younger-looking man. The effects on Lazarus' DNA causes him to sporadically transform into a giant creature that sucks the life force from other victims.

According to the BARB figures this episode was seen by 7.19 million viewers and was the twelfth most popular broadcast on British television in that week.^[1] Executive producer Russell T Davies has stated that he directed writer Stephen Greenhorn to base this episode on the typical Marvel Comics plotline: "a good old mad scientist, with an experiment gone wrong, and an outrageous supervillain on the loose."^[2]
