Which film adaptation of a J.K. Rowling book was the first to be directed by David Yates?

Harry Potter and the Order of the Phoenix was the first film adaptation of a J.K. Rowling book directed by David Yates.

Released in 2007, Harry Potter and the Order of the Phoenix followed four earlier films directed by Chris Columbus, Alfonso Cuarón, and Mike Newell. David Yates then directed the remaining Harry Potter films, including Harry Potter and the Half-Blood Prince and the two-part adaptation of Harry Potter and the Deathly Hallows.

The film stars Daniel Radcliffe, Rupert Grint, and Emma Watson, with Imelda Staunton as Dolores Umbridge. Its story centers on Harry's formation of Dumbledore's Army while the Ministry of Magic denies Voldemort's return. The film is based on the fifth novel, not the sixth; that distinction is an easy way to separate Order of the Phoenix from Half-Blood Prince, which Yates also directed.
