- "The good sisters of St. Bernadette's taught me a lot. But I was never an establishment kinda gal."
- ―Harley Quinn[src]
St. Bernadette's Orphanage is an orphanage in Gotham City.
At a young age, Harleen Quinzel was illegally traded by her father for a six-pack of beer, but no matter how many times he tried to ditch her, she always found her way back. Eventually, her father sent her to St. Bernadette's, where she was punished by the sisters, smacking her on the rear with a paddle board. She would later grow tired of this and take revenge on one of the sisters, hitting her in the head with the same paddle board they used on her.
