Helluva Boss is an American adult animation Musical film black comedy web series created by Vivienne Medrano. It revolves around the misadventures of the employees of I.M.P., a company in Hell that offers hitman services in the realm of the living. The pilot was released on November 25, 2019, before the series premiered on October 31, 2020.
Set in the same fictional universe as Hazbin Hotel, the show is produced by SpindleHorse. The first season was released exclusively on Medrano's YouTube channel. The second season premiered on July 30, 2022. A spin-off short series titled Helluva Shorts was also released in April 2024. In April 2025, it was announced that the third and fourth seasons will be released on Prime Video first, subsequently releasing on YouTube a month after. A reimagining of the pilot, titled "Mission Zero", was released to Prime Video on September 10, 2025, alongside a re-release of the first two seasons, all of which are fully uncensored. "Mission Zero" was released to YouTube on October 25.
The show features a different cast of characters and a different storyline than Hazbin Hotel, another show created by Medrano, despite taking place within the same universe. As Medrano described it, while both shows share the same setting, Helluva Boss follows "characters and societies that already exist in Hell", with the main focus being on interpersonal relationships between characters, while Hazbin Hotel is about redemption and consequences.

On November 25, 2019, the Television pilot was released on Medrano's YouTube channel. Medrano contributed her writing and animation skills to the episode. Writing production for more episodes began in December 2019, with 8 episodes ordered. The company Horseless Cowboy assisted Medrano with voice work during the first season, with Richard Horvitz and Medrano voice directing. In August 2020, the recording for season 1 was completed, and Lucas Bermudez of Screen Rant predicted that more episodes of Helluva Boss would be released to YouTube "as a web series" because of the COVID-19 pandemic.
On October 31, 2020, the first episode of season 1 was released. In the episode, Rogers and Horvitz return as Blitzo and Moxxie, and while Lindbeck returns as Loona, she is replaced by Vivian Nixon as the voice of Millie. Baker was replaced by Bryce Pinkham as Stolas. Guest stars of the episode include Monsoon, Mara Wilson, and Maxwell Atoms. On January 31, 2021, the third episode of the series was age-restricted by YouTube. In response, entertainment site Newgrounds offered to host an Censorship version of the episode and promote it with "a front page banner", something which Medrano expressed interest in.

Zoe Dumas of MovieWeb argued that the series has "emotionally complex" characters, a talented and musical voice cast, and "outstanding" animation. Dumas also argued that the series is "more episodic and character-driven" than Hazbin Hotel, while complimenting the latter. Joshua S. Mackey for Into praised the series for having "three different queer main characters".
In February 2021, Medrano told Insider that Helluva Boss remains independent of Hazbin Hotel, stating she intends to keep it that way "as long as the audience wants to keep seeing it", adding that she has "a plan for where the story goes and ends". It also states that she has "carved out a niche for adult animation on the platform". In 2023, scholar Ben Mitchell described the series as "sensationally popular" and an effective use of Patreon to subsidize the show's art "through monthly tiered payments". Zoe Dumas of MovieWeb described the series as a "wild success" with a "superb voice cast".
