Is there anything at the end credits of Harry Potter and Deathly Hallows part 2?

No, there is no extra scene or credit scene at the end of Harry Potter and the Deathly Hallows Part 2. The film concludes with the final scene of Harry, Ron, and Hermione returning to Hogwarts, 19 years after the Battle of Hogwarts.

It's a fitting end to the series, leaving no room for a post-credits scene.
