Summary
During another summer with his Aunt Petunia and Uncle Vernon, Harry is whisked off by a group of wizards to Number 12, Grimmauld Place, the home of his godfather, Sirius Black. The house also serves as the headquarters of the Order of the Phoenix. Ron and Hermione explain that the Order of the Phoenix is a secret organisation led by Dumbledore, dedicated to fighting Lord Voldemort.
At Hogwarts, Harry learns that Dolores Umbridge, a senior employee under the Minister of Magic, will be the new Defence Against the Dark Arts teacher. Umbridge and Harry clash, as she, like Fudge, refuses to believe that Voldemort has returned. She punishes Harry for his rebellious outbursts by having him write "I must not tell lies" with a cursed quill that carves the phrase into his skin. She also refuses to teach her students how to perform defensive spells, prompting Harry, Ron and Hermione to form their own Defence Against the Dark Arts group, which they call Dumbledore's Army. The club meets in the Room of Requirement to learn and practice Defence spells under Harry's instruction.

Umbridge finally sacks Professor Trelawney, the Divination teacher; However, she is outraged when Professor Dumbledore undermines her power by allowing Trelawney to continue living at the school, and hires Firenze, a centaur, to take her place, in spite of Umbridge's prejudice against part-humans. Suspecting that he will be next, Hagrid confesses to Harry, Ron and Hermione that he has brought his giant half-brother, Grawp, to Hogwarts, and hidden him in the Forbidden Forest. Hagrid asks the three of them to look after Grawp if he must leave the school. Sure enough, Umbridge leads a party of Aurors to attack Hagrid in his house one night. Hagrid overpowers them and flees the school. McGonagall, trying to disrupt the violence, is badly injured and is put in St. Mungo's Hospital.
One night, Harry has a vision through the eyes of Voldemort's snake Nagini, possessed by Voldemort, attacking Ron's father Arthur Weasley. Harry informs Professor McGonagall and Dumbledore, and Mr. Weasley is rescued. Dumbledore arranges for Harry to take Occlumency lessons with Professor Snape to protect his mind against further invasions by Voldemort. One evening, Umbridge is given a tip-off about Dumbledore's Army by Marietta Edgecomb. When Dumbledore takes responsibility for the illegal organization, he is forced to leave the school and go into hiding. Dolores Umbridge becomes headmistress, and Fred and George cause pandemonium around the school in revenge. They eventually leave Hogwarts to start a joke-shop in Diagon Alley.

On the last day of OWL tests, Harry has a vision of Sirius being tortured by Voldemort in the Department of Mysteries. He tries to illegally use Umbridge's office fire to communicate with the Order of the Phoenix's headquarters to make sure the vision was genuine, and is told by Kreacher the house-elf that Sirius is indeed at the Ministry. Umbridge catches Harry and his friends in the act and, when told that Snape has no more truth potion, intends to use the illegal Cruciatus Curse on Harry to interrogate him on Sirius's whereabouts. She also reveals she herself ordered the dementor attack on him. Hermione intervenes and in order to create a distraction, convinces Umbridge than they are hiding a weapon of Dumbledore's in the Forbidden Forest. Harry and Hermione lead her into an area of the forest inhabited by centaurs, where Umbridge provokes them into taking her captive. Grawp arrives and clashes with the centaurs, allowing Harry and Hermione to escape.
Luna, Ron, Ginny, and Neville join them in the forest and all six fly to the Ministry on thestrals, expecting to find and rescue Sirius. Once in the Department of Mysteries, Harry realizes that his vision was falsely planted by Voldemort; however, he finds a glass sphere that bears his and the Dark Lord's names. Death Eaters led by Lucius Malfoy attack in order to capture the sphere, which is a recording of a prophesy concerning Harry and Lord Voldemort; it becomes clear that this was why Harry was lured there, since only the subjects of the prophesies can remove them from the shelves. Harry and his friends, soon joined by members the Order, enter a battle with the Death Eaters. Amidst the chaos, Bellatrix Lestrange kills Sirius and Harry faces Voldemort. Voldemort escapes just as Cornelius Fudge appears, finally faced with first-hand evidence that Voldemort has truly returned.
In his office, Dumbledore explains to Harry that the prophecy states that Harry and Voldemort must eventually face each other and fight to the death: "for neither can live while the other survives".
