Molly Caitlyn Quinn (born October 8, 1993 in Texarkana, Texas) is an American actress—credited as Molly C. Quinn since 2013—whose work includes theatre, film, and television. Her notable roles include Alexis Castle, daughter of the title character, on ABC's Castle and the voice of Bloom, one of the main characters in Winx Club.


Quinn began taking weekly acting lessons from retired director and producer Martin Beck after performing in her community's performance of The Nutcracker at age six. In the sixth grade, she auditioned at the Young Actors Studio where she performed for the program's director, Linda Seto, and representatives from the Osbrink Talent Agency. After six months of "intensive [acting] training", Quinn signed a contract with the Osbrink agency. Subsequently, she signed with Management 360.

From 2009 to 2016, she starred in the ABC mystery drama series Castle as Alexis Castle, the lead character's daughter. In early 2012, Quinn began the English-overdub role of Princess Bloom in the Nickelodeon version of the film Winx Club: The Secret of the Lost Kingdom. In 2011, she continued the role in the Winx Club Nickelodeon TV series. In March 2014, Quinn appeared as the voice of the sentient computer 'Fey', in the episode "Numbers" of the podcast series Welcome to Night Vale.
