Katie Liu Leung (Chinese: ???, born 8 August 1987 in Scotland) is a Scottish actress of Chinese descent who is playing the character of Cho Chang, Harry Potter's love interest, in the movie version of the J. K. Rowling novel, Harry Potter and the Goblet of Fire, released in cinemas November 18, 2005. Leung lives in Motherwell, a town near Glasgow. Her parents are separated and she currently resides with her father Peter Leung (a native from Hong Kong), two brothers (one is called Jonathon) and a younger sister. After her father saw an advert on television, which called for girls of East Asian appearance to audition for the role of Cho Chang in London, she travelled out of her native Scotland to try her luck, and for a bit of shopping. Leung was selected out of more than 4,000 other hopefuls in the auditions for the part of Cho Chang. Her distinct Scottish accent was one of the main deciding factors in securing her the part.

Relatively little is known about the actress at this point. Daniel Radcliffe, the actor playing Harry Potter, noted that he found Leung to be "awesome" and a "really good actress."
