Christian Horner long held the title of the longest-serving team principal on the F1 grid, but that bragging right has now disappeared following his departure from Red Bull.
Horner joined the Milton Keynes-based team as team principal in 2005 as the squad embarked on its first season on the grid.
The Briton oversaw a hugely successful period for the team, who won eight drivers' titles, six constructors' championships and 124 race wins under his leadership.
However, Horner was shown the exit door midway through the 2025 campaign, bringing an end to his 20-year association with the team.
Mercedes team boss Toto Wolff now holds the accolade of the longest-serving team principal on the grid, having taken over at the helm of the squad in 2013.
There is a large gap to the next figures on the list with Andrea Stella, Fred Vasseur and James Vowles all ascending to the head roles at McLaren, Ferrari and Williams respectively in early 2023.
See the longest-serving team principal list below!
