The Hogwarts house named after Helga Hufflepuff is Hufflepuff.
Hufflepuff is one of the four student houses at Hogwarts School of Witchcraft and Wizardry. It was founded by Helga Hufflepuff, one of Hogwarts’ four founders. The house is associated especially with hard work, patience, loyalty, and fair play.
Its students are traditionally identified by yellow and black, and its emblematic animal is the badger. The house common room is located near the kitchens, in the basement area of Hogwarts. These details distinguish Hufflepuff from the other three houses: Gryffindor, Ravenclaw, and Slytherin.
Important Hufflepuff characters include Cedric Diggory, a Hogwarts champion in Goblet of Fire, and Nymphadora Tonks, an adult witch and member of the Order of the Phoenix. New students are assigned to houses by the Sorting Hat, which considers their qualities and, in some cases, their preferences.
