The NCIS Star Who Outlasted Them All: You’ll Never Guess Who It Is!

With NCIS running for over two decades, many stars have come and gone, but one actor has remained a constant presence—Sean Murray, who plays Timothy McGee. While fans might initially guess Mark Harmon, who led the series for 19 seasons, it’s actually Murray who has quietly become the longest-running NCIS cast member. First appearing in Season 1 as a recurring character, McGee was promoted to a main role in Season 2 and has been a staple ever since.

Murray’s longevity is a testament to his character’s growth, evolving from a rookie agent to a seasoned leader within the team. His ability to adapt and remain integral to the show has solidified his place as an NCIS icon. While other major cast members, including Harmon, Pauley Perrette, and Michael Weatherly, have exited, Murray continues to be a steady presence, making him the true NCIS veteran who outlasted them all.
