Michael J. Fox, the beloved actor best known for Back to the Future, holds one role closest to his heart: being a dad. He’s been married to actress Tracy Pollan for more than 30 years, and together they’ve raised four children.

Even while living with Parkinson’s disease—a diagnosis he’s faced since 1991—Fox remains deeply devoted to his family. He treasures every moment with his kids and makes it a priority to stay present in their lives.

His love for his family often shines through on social media and was front and center in his 2023 documentary, Still: A Michael J. Fox Movie. Here’s a look at the family that means the world to him.
