Gilmore Girls was filmed at Warner Bros. Studios in Burbank, California. While the pilot episode was shot in Unionville, Ontario, all subsequent episodes were filmed on sets designed to replicate the quaint, fictional town of Stars Hollow. Key locations like Luke’s Diner, the Dragonfly Inn, and the town square were all part of the studio backlot. Additionally, some exterior scenes were filmed at Greystone Park and Mansion in Beverly Hills, and UCLA stood in for Harvard in certain episodes​.
