Lisa Glendon, played by Valerie Hobson, is a character from the 1935 film Werewolf of London.
Lisa is the wife of botanist Wilfred Glendon. Wilfred often becomes obsessed with his work and neglects Lisa, though she seems to try to keep their marriage going. While Wilfred was away in Tibet, he was bitten by a werewolf, later revealed to be Dr. Yogami.
When Wilfred is again working at home, Lisa attends her aunt Ettie's party with her friend, former childhood sweetheart Paul Ames, allowing the swiftly transforming Glendon to make his way unhindered to his at-home laboratory, in the hopes of acquiring the mariphasa's flowers to quell his lycanthropy.
Not knowing that Wilfred will instinctively attack the person he most loves, Lisa is in danger.
After attacking Paul on the front lawn of Glendon Manor, but not killing him, Glendon breaks into the house and corners Lisa on the staircase and is about to move in for the kill when Paul's uncle, Col. Sir Thomas Forsythe of Scotland Yard, arriving with several police officers in tow, shoots Glendon once. As he lies dying at the bottom of the stairs, Glendon, still in werewolf form, speaks: first to thank Col. Forsythe for the merciful bullet, then saying goodbye to Lisa, apologizing that he could not have made her happier. Glendon then dies, reverting to his human form in death.
