Gerry Davis was a British television writer, best known for his contributions to the science-fiction genre. He also wrote for the soap operas Coronation Street and United!.

From 1966 until the following year, he was the script editor on the popular BBC science-fiction series Doctor Who, for which he co-created the popular cybernetic monsters known as the Cybermen, who made several appearances in the series over the following twenty-two years. His fellow co-creator of these creatures was the programme's unofficial scientific adviser Dr. Kit Pedler, and following their work on Doctor Who, the pair teamed up again in 1970 when they created a science-fiction programme of their own, Doomwatch. Doomwatch ran for three seasons on BBC One from 1970
