iCarly is an American teen sitcom created by Dan Schneider, which originally aired on Nickelodeon from September 8, 2007, to November 23, 2012. The series tells the story of Carly Shay (Miranda Cosgrove), a teenager who creates and hosts her own web show called iCarly with her best friends Sam and Freddie (Jennette McCurdy and Nathan Kress) in the apartment loft that she and her older brother Spencer (Jerry Trainor) live in. As the web show quickly becomes an internet phenomenon, the characters are tasked with balancing their normal teenage lives with the wacky situations their newfound fame lands them in. By the fourth season, their school friend Gibby (Noah Munck) also works with them on the web show.

Schneider was both the showrunner and executive producer, under his Schneider's Bakery label. During the first five seasons, the show was taped at Nickelodeon on Sunset before relocating to KTLA Studios in Hollywood for the sixth and final season. It was nominated for an Emmy award for Outstanding Children's Program five times. Although the show received mixed reviews from critics, it became popular with audiences. The January 2010 episode "iSaved Your Life" reached 11.2 million viewers, the second most viewed telecast in Nickelodeon history.

In December 2020, a revival of the series was ordered by Paramount+ with Cosgrove, Kress and Trainor returning. The revival series premiered on June 17, 2021.
