Which Harry Potter book did J.K. Rowling write after Harry Potter and the Goblet of Fire?

Harry Potter and the Order of the Phoenix followed Harry Potter and the Goblet of Fire in J.K. Rowling’s series. It was published in 2003 as the fifth main novel.

The book returns Harry to Hogwarts for his fifth year and introduces Dolores Umbridge, a Ministry of Magic official appointed as the school’s High Inquisitor and later Headmistress. Harry also forms Dumbledore’s Army, a student group that practices defensive magic in response to the school’s restrictions.

Order of the Phoenix was followed by Harry Potter and the Half-Blood Prince in 2005 and Harry Potter and the Deathly Hallows in 2007. Readers sometimes confuse its position because the title refers to an organization rather than a school year or a magical object. The Order itself is a resistance group founded by Albus Dumbledore.
