Madelaine "Maddie" Hasson (born January 4, 1995) is an American actress. She is best known for her role as Willa Monday on the Fox television series The Finder. She portrays Jo Masterson on Twisted.

Since the age of seven, Hasson has danced, sung, and acted in pursuit of her dreams while living in her hometown of Wilmington, North Carolina. She has won numerous awards, including the prestigious choreographer Mia Michaels Scholarship at the Broadway Dance Center, and she was the Triple Threat Winner at Access Broadway. But it’s in acting where she found her true passion. Performing back to back in diverse roles in Cape Fear Academy productions and her local professional theatre, The Opera House Theatre, Hasson won praise for her performances in Best Little Whorehouse in Texas, A Midsummer Night’s Dream, Anything Goes, Antigone, Vital Signs and Grey Gardens.
