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.

Victoria first appeared in the 1967 serial The Evil of the Daleks. She was the daughter of scientist Edward Waterfield, who in 1866 was experimenting with time travel and attracted the attention of the Daleks. At the conclusion of that adventure, Waterfield was killed saving the Doctor's life, and asked him to take care of Victoria. The Doctor and his then-current companion Jamie took her in as part of the TARDIS crew.

On the outside, Victoria was a typically fragile lady of her era, frequently screaming when faced with the creatures the Doctor and his companions encountered in their travels, like the Cybermen and the Yeti, the latter which were automatons of the disembodied Great Intelligence. However, this exterior hid an inner strength that cropped up when it was needed. Victoria may have been young, but she had an instinct for when she was being lied to, and her sensibility was a contrast to the recklessness of Jamie and the curiosity of the Doctor. Jamie, in particular, was very protective and fond of Victoria, and was heartbroken when she chose to leave.

Despite being a good match to her two companions, Victoria eventually found herself unsuited to extended travel with the Doctor. At the conclusion of the serial Fury from the Deep , she decided to leave the TARDIS, settling with a family named Harris in the 20th Century. Her subsequent life was not shown in the television series, but in the spin-off video and novel Downtime, an older Victoria comes to grapple with the Great Intelligence once more, with the help of Brigadier Lethbridge-Stewart and Sarah Jane Smith. She is mentioned, but not seen to be travelling with the Second Doctor in the 1985 serial The Two Doctors (see Season 6B).

Deborah Watling reappeared as Victoria in the 1993 charity special Dimensions in Time.
