Milo Murphy's Law Wiki

Zack: Yeah, grandparents are the best. Hey, are yours full of great stories and wise advice?
Sara: They might be. There's no way of telling.

Zack Underwood and Sara Murphy

Grandpa Murphy is the father of Martin and Joey Murphy, the husband of Grandma Murphy, the grandfather of Nate, Milo, and Sara, and father-in-law of Brigette.

He is voiced by the late Fred Willard.


He and his wife have a habit of talking over each other, but it can be discerned that he is kind and loving towards his family. He is proud to have EHML and tried to express this attitude to Nate after he'd claimed he didn't have it.

Physical Appearance

Grandpa Murphy is an elderly man with dark grey hair, brown eyes, and a mustache. In "A Christmas Peril", he wore a brown jacket with multiple pockets, a blue scarf, and a fluffy brown cap alongside a pair of large glasses.


In "A Christmas Peril", Milo picks his grandparents up at the train station, where they're promptly trapped on the train with him and Nate. Eventually, Murphy's law causes the train to fall on its side, and the group continues on to pick up the rest of the Murphys. They end up reuniting with the other Murphys at the mall, where they enjoy a Christmas Eve dinner together.

In "Now I Am a Murphy", he arrives to help Martin put Milo through the trials of becoming a Murphy man. To do so, the three of them go on a trip together.
