* Dobby: He appears briefly, warning Harry about the dangers ahead and offering his services as a protector. This is his last appearance in the films before his heroic sacrifice.
* Kreacher: Harry, Ron, and Hermione bring Kreacher with them to 12 Grimmauld Place as their house-elf. While initially resentful, Kreacher becomes increasingly helpful and even demonstrates loyalty and courage.
* Winky: Winky is mentioned by Kreacher as being "mad" after Barty Crouch Jr. was sent to Azkaban. She is also shown in a flashback sequence from the previous film, "Harry Potter and the Goblet of Fire."
While other house-elves might be present in the wizarding world during this time, they are not explicitly shown in the film.
