SpindleHorse, doing business as SpindleHorse Toons, is an American independent animation studio founded by Vivienne "VivziePop" Medrano in 2018, based in Burbank, California. It is responsible for the Hellaverse shared universe animated series, whose main series Hazbin Hotel is co-animated with Bento Box Entertainment and co-produced with A24. It was the sole animation studio of its spin-off series, Helluva Boss until 2025, when Amazon Prime offered to co-produce Helluva Boss.

SpindleHorse has also produced several animated shorts, including Holidaze and Bad Luck Jack, all of which are available on Medrano's YouTube channel. Medrano has stated that the company's name comes from a childhood character of hers named Spindle.
