The Loud House is an American animated television series created by Chris Savino that premiered on Nickelodeon on May 2, 2016. The series revolves around the chaotic everyday life of a boy named Lincoln Loud, who is the middle child and only son in a large family of 11 children. It is set in a fictional town in southeastern Michigan called Royal Woods, based on Savino's hometown of Royal Oak. The series was pitched to the network in 2013 as a two-minute short film entered in the annual Animated Shorts Program. It entered production the following year. The series is based on Savino's own childhood growing up in a large family, and its animation is largely influenced by newspaper comic strips.

Since its debut, the series has gained high ratings, becoming the top-rated children's animated series on American television within its first month on the air. The series has received considerable media attention and nominations at both the 28th and the 29th GLAAD Media Awards for its inclusion of Howard and Harold McBride, two supporting characters who are an interracial gay married couple.

In May 2017, the characters of Lincoln Loud and Clyde McBride were featured on the front cover of Variety as an example of diverse characters in children's television.As of May 2023, seven seasons of the series have been broadcast. The series has spawned a multimedia franchise, including the spin-off series The Casagrandes, which aired from October 2019 to September 2022, an animated feature film that was released on Netflix in August 2021, a live-action television film that premiered in November 2021, and live-action series The Really Loud House that premiered in November 2022.
