It’s a question that’s popped up time and time again—are Rizzoli & Isles star Angie Harmon and NCIS legend Mark Harmon actually related? With both actors sharing the same last name and building successful careers in crime dramas, many fans have long assumed there must be a family connection. But the truth might surprise you.

Despite the coincidence in names and careers, Angie Harmon and Mark Harmon are not related. They come from entirely different backgrounds and family trees. Mark Harmon, born in California, is the son of football star Tom Harmon and actress Elyse Knox. Angie Harmon, on the other hand, hails from Texas and has no known familial ties to the Harmon acting dynasty.

The confusion is understandable—both stars rose to prominence on hit TV shows where they played strong, law-enforcing characters. Mark Harmon spent nearly two decades as Special Agent Leroy Jethro Gibbs on NCIS, while Angie Harmon won over fans as Detective Jane Rizzoli. Their strong screen presence, similar last names, and overlapping TV fame only fueled the speculation.

So while they may share the same last name and a passion for television drama, that’s where the similarities end. Angie and Mark Harmon are connected by talent and success—not by blood.
