Joanna Beth Harvelle is a fictional character on The CW Television Network's drama/horror television series Supernatural portrayed by Alona Tal. Aspiring to be a hunter of supernatural creatures like her parents, she was introduced in the second season in order to explore a mother-daughter relationship in the hunting world. She was ultimately removed from the series by the end of the second season—Kripke admitted the conception of the character was flawed from the beginning—but returned in the fifth and seventh seasons.
