Thea Dearden Queen, also known as Speedy, is a fictional character portrayed by Willa Holland on The CW television series Arrow, created by Greg Berlanti, Marc Guggenheim, and Andrew Kreisberg. She is the maternal half-sister of series protagonist Oliver Queen / Green Arrow. Although an original creation to the series, she adopts elements from the DC Comics superhero Mia Dearden / Speedy, created by writer Kevin Smith and artist Phil Hester.

Holland was a main cast member on Arrow from its first season until its sixth, and also crossed over to the spin-off Arrowverse series The Flash. Although Thea Queen is loosely inspired by the existing comics character Mia Dearden, a sidekick of Green Arrow, the idea of Green Arrow working alongside his archer half-sister was later incorporated back into the comics in the form of Emiko Queen.

Thea Queen was born on January 21, 1995 in Starling City to Robert and Moira Queen, (although it is later revealed that Thea is Malcolm Merlyn's biological daughter ) and the younger half-sister of Oliver Queen. Though Malcolm was unaware that Thea was his daughter, and Thea was likewise in the dark, Robert was aware but still loved Thea like his own. When her father and brother were both presumed dead, Thea felt alone and disconnected from the world. She fell into a life of drugs and partying to fill the void left by her father and brother.

Thea is introduced as a senior in high school who is grateful to have her big brother back, but his disappointment in her lifestyle and the secrets he keeps from her about his five years away cause her to slip even further into drug use. On her 18th birthday, she is involved in a car crash while on the narcotic Vertigo and is subsequently arrested and sentenced to community service for 500 hours at CNRI (City Necessary Resources Initiative) under the supervision of Laurel Lance. Her addiction to Vertigo causes an animosity between her returned brother's alter-ego the Arrow and the drug's creator the Count.

Thea Queen (Arrow) has not been a contender in any CBUB matches.
