Hazbin Hotel is an American adult animated musical comedy television series created by Vivienne "VivziePop" Medrano. The series revolves around Charlie Morningstar, princess of Hell, on her quest to find a way for sinners to be "rehabilitated" and allowed into Heaven, via her "Hazbin Hotel", as an alternative to Heaven's annual "Extermination" of wayward souls due to Hell's overpopulation. The series is produced by independent entertainment company A24 and animation studio Bento Box Entertainment, in collaboration with Amazon Studios.

The pilot, released on YouTube on October 28, 2019, was made entirely by freelance animators and was largely financed by Medrano's Patreon followers. The first season premiered on Amazon Prime Video on January 18, 2024, with its first episode also released on YouTube on that same day for a limited release. A second season is confirmed to be in production. It has received generally positive reviews from critics.

The popularity and success of the pilot allowed Medrano to create a spin-off series called Helluva Boss, which premiered on October 31, 2020. The series features a different cast of characters within the same in-universe setting.

On January 26, 2024, it was revealed that Hazbin Hotel is the largest global debut for a new animated series on Prime Video.
