Hela is a fictional character appearing in American comic books published by Marvel Comics. She is based on the goddess Hel from Norse mythology, and was first adapted by Stan Lee and Jack Kirby in Journey into Mystery #102. Hela is the Asgardian Goddess of Death who serves as the ruler of Hel and Niflheim. The character is usually depicted as an adversary of the superhero Thor.

Hel is a female being in Norse mythology who is said to preside over an underworld realm of the same name, where she receives a portion of the dead. Hel is attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources, and the Prose Edda, written in the 13th century. In addition, she is mentioned in poems recorded in Heimskringla and Egils saga that date from the 9th and 10th centuries, respectively. An episode in the Latin work Gesta Danorum, written in the 12th century by Saxo Grammaticus, is generally considered to refer to Hel, and Hel may appear on various Migration Period bracteates.
