Victoria Waterfield is a fictional character played by Deborah Watling in the long-running British science fiction television series Doctor Who. A native of Victorian England, she was a companion of the Second Doctor and a regular in the programme from 1967 to 1968. Only two complete serials to feature her exist complete in the BBC archives. However, DVDs of all her adventures have still seen release, with both official animation and photo reconstructions utilizing the original surviving audio taking the place of the missing episodes.

The Tomb of the Cybermen is the first serial of the fifth season of the British science fiction television series Doctor Who, which was originally broadcast in four weekly parts on BBC1 from 2 to 23 September 1967.
