Elizabeth Lavenza is a character in the film Frankenstein (Mae Clark) and Bride of Frankenstein (Valerie Hobson).
Elizabeth worries when Henry secludes himself in his laboratory and refuses to see anyone, and begs his mentor, Professor Waldman, to talk some sense into him. After his experiments get out of control, Henry departs the laboratory and returns home to his ancestral village. The monster runs loose on the day of the wedding, and Henry tells Elizabeth to stay in one of the rooms. The monster climbs through the window and frightens her so badly that she faints. She is last seen by Henry's bedside as he recovers from his climactic battle with the monster.
In Bride of Frankenstein, Elizabeth and Henry are married. She is kidnapped by the monster as a means of making Henry agree to create the Monster a mate. When the monster decides to destroy Frankenstein Castle with himself, his bride and the evil Dr. Septimus Pretorious inside, he allows Henry and Elizabeth to leave. The couple are last seen holding each other as the castle burns down.
