Geneviève Elverum (née Gosselin; April 9, 1981 – July 9, 2016), also known as Geneviève Castrée, was a Canadian cartoonist, illustrator, and musician from Quebec. An early admirer of comics, she began creating them at a young age. L'Oie de Cravan published her first book, Lait Frappé, in 2000. By 2004 she had released three more books—Die Fabrik, Roulatheque Roulatheque Nicolore and Pamplemoussi. The latter is considered her artistic breakthrough.

Her 2012 book Susceptible gave her international success and was followed by a book of poems in French entitled Maman Sauvage in 2015. Her next two works A Bubble and Maman Apprivoisée were both released posthumously. She also recorded a total of eight albums under the name Woelv and Ô Paon (stylized in all caps).

In 2003, Castrée met musician Phil Elverum, and the two married the following year. In 2015, she gave birth to their only child. That same year, she was diagnosed with pancreatic cancer. She died in 2016. Elverum later recorded a series of albums centered around her life and death.
