Cho Chang is a fictional character in J. K. Rowling's Harry Potter series of novels. She is a year older than Harry and the Seeker for the Ravenclaw Quidditch team and is described as being very pretty and popular. Her name seems to imply Eastern Asian descent, possibly Chinese.

Cho will be played by Katie Leung in the fourth Harry Potter movie, Harry Potter and the Goblet of Fire.

During Harry's fourth year , he had a crush on Cho and asked her to the Yule Ball. Unfortunately Cedric Diggory, Hufflepuff's Seeker, asked her first, and she dated Cedric until he was murdered by Peter Pettigrew on Lord Voldemort's orders.

During Harry's fifth year , Hermione Granger says that, due to Cedric's death, Cho frequently cries. Cho and her friend, Marietta Edgecombe, join Dumbledore's Army, even though both their parents said to stay on Dolores Umbridge's good side. Cho joined because Harry was teaching and because of what happened to Cedric. Harry and Cho share a kiss under some mistletoe, and on Valentine's Day went on a date of sorts in the wizard's village of Hogsmeade, but Cho's continued grief over the death of Diggory, her jealousy of Harry's friendship with Hermione, and his seeming inexperience in matters of the heart soured the experience.

When Marietta Edgecombe betrays Dumbledore's Army, she is afflicted by the hex Hermione placed on the parchment each member of Dumbledore's Army signed, leaving the word "sneak" on her forehead. When Harry blames Marietta, Cho defends her, irate at what she considers Hermione's dirty trick; this cools Harry and Cho's relationship considerably.

After the death of Sirius Black, Harry comments that his feelings for Cho have abated, perhaps because of his changed worldview. At the end of Harry's fifth year, Ginny Weasley reveals that Cho is dating Ginny's ex-boyfriend, Michael Corner.
