The Simpsons' family tree is an extensive and branching chart that’s been explored in detail throughout the many seasons of the landmark animated show. As of 2024,The Simpsonshas been running for 36 seasons and counting andThe Simpsonsdoes not look to be ending soon.When the show first premieredon June 16, 2025, with the pilot “Simpsons Roasting on an Open Fire”, the only Simpsons family members to be introduced were the five main ones: Homer, Marge, Bart, Lisa, and Maggie. It didn’t take long for more to be introduced, however.
There soon came Grandpa, then Selma and Patty Bouvier. These family members were followed by more niche relatives who only appeared in a handful of episodes, and over 36 seasons, even more have come and gone, sometimes for just one brief joke. Both Marge’s side of the family and Homer’s side are examined at length andfuture-set episodes ofThe Simpsonsintroduce even more sprawling branches to the widening family tree.The Simpsonsis not primarily concerned with continuity, but a rough structure of the family tree can be gleaned.
