The Really Loud House is an American sitcom developed by Tim Hobert that aired on Nickelodeon from November 3, 2022 to November 26, 2024. It is a live-action spin-off of the animated series The Loud House, created by Chris Savino, and the third television series in the overall franchise, utilizing most of the actors that appeared in the 2021 television film A Loud House Christmas, including Wolfgang Schaeffer, Jahzir Bruno, Sophia Woodward, Catherine Ashmore Bradley, Aubin Bradley, Lexi Janicek, Ella Allan, Mia Allan, Lexi DiBenedetto, and Brian Stepanek, with Eva Carlton, Annaka Fourneret, August Michael Peterson, and Jolie Jenkins joining the cast.

In addition to developing the series, Hobert serves as an executive producer alongside his brother Michael Hobert, Michael Rubiner (an executive producer of the original animated series), primary episode director Jonathan Judge, and the writing duo of David McHugh and Matt Flanagan. Don Dunn and frequent series writer Angela Yarbrough serve as producers, with Melanie Kirk and Debra Spidell serving as co-producers during seasons 1 and 2, respectively. The writing staff consists of the Hobert brothers, their sister Audrey Hobert, Amy Pittman, Peter Limm, Alan Yanaga, and John Dale. Limm has served as story editor for the show's entire run, and Yanaga joined him for the second season. Yarbrough, McHugh and Flanagan, and David S. Rosenthal have also written for the series. Rosenthal became consulting producer in the second half of the show's first season and remained for the second season. The directing staff so far includes Judge, Melissa Kosar, David Kendall, Phill Lewis, Daniella Eisman, Carlos González, and Julian Petrillo.
