Wendy Padbury is a British actress from Warwickshire, England, best know for playing Zoe alongside Second Doctor Patrick Troughton.

Padbury came to prominence in 1966 when she joined the cast of the long-running ATV soap opera Crossroads after she came second in the television talent contest "Search For A Star". She played the role of Stephanie "Stevie" Harris, foster daughter to the show's main character, Meg Mortimer (Noele Gordon).

She was cast as the Second Doctor's new companion, Zoe Heriot, in Doctor Who in 1968. She became very close to her co-stars Frazer Hines and Patrick Troughton, the latter playing the Doctor. 

Her connection with Doctor Who after she left the programme (at the same time as Hines and Troughton) was not quite over. She appeared in Doctor Who and the Daleks in the Seven Keys to Doomsday (1974), a stage play at the Adelphi Theatre London based on the television series, in which she played a companion named Jenny, opposite Trevor Martin as the Doctor. She then made a cameo appearance, again with Hines and Troughton in Doctor Who's 20th anniversary story, The Five Doctors.

Other roles include co-presenter of the second series of Score With The Scaffold. She appeared in three series of the children's television adventure programme Freewheelers playing the part of Sue Craig. In 1971 Padbury appeared in Piers Haggard's cult British horror film Blood on Satan's Claw as the unfortunate Cathy Vespers. 

She later became a theatrical agent with Nicholas Courtney, Colin Baker and Mark Strickson, all former Doctor Who actors, amongst her clients. She discovered Matt Smith at the National Youth Theatre.

Padbury was for a time married to Melvyn Hayes
