What is the name of the host of the reality competition show 'American Idol'?

What is the name of the host of the reality competition show 'American Idol'? Ryan Seacrest is the show’s principal and longest-serving host. He has presented American Idol across its original Fox run and its later revival on ABC.

American Idol premiered in the United States in 2002 as an adaptation of the British format Pop Idol. Its first season used two presenters: Seacrest and comedian Brian Dunkleman. Dunkleman left after that season, making Seacrest the sole host from season two onward. That early co-hosting arrangement is the main reason some references mention both names.

The show’s judges—including Randy Jackson, Paula Abdul, and Simon Cowell—are not hosts. They evaluate contestants, while Seacrest guides auditions, results shows, performances, and finale broadcasts. This distinction also rules out the three names commonly offered as alternatives.

Seacrest continued hosting when American Idol moved from Fox to ABC in 2018. The program’s winners have included Kelly Clarkson, Carrie Underwood, and other singers, but the presenter has remained a consistent part of the show’s identity.
