Albus Dumbledore - Headmaster of Hogwarts. He is a central figure, guiding Harry in his fight against Voldemort through private lessons about Horcruxes. His role is more active in this book, although his health deteriorates due to a curse.
Minerva McGonagall - Transfiguration Professor and head of Gryffindor. Loyal to Dumbledore, she maintains his strict but fair authority. She assumes a more prominent role towards the end due to key events in the plot.
Severus Snape - Defense Against the Dark Arts Professor (after years of teaching Potions) and Head of Slytherin. His appointment as Defense Against the Dark Arts Professor is significant, and his loyalties remain ambiguous until the final events, where his role is crucial.
Horace Slughorn - New Potions professor. He returns to Hogwarts after being persuaded by Dumbledore. He is a charismatic character, a collector of talented students, and provides a key memory about Voldemort and the Horcruxes.
Rubeus Hagrid - Care of Magical Creatures professor and gamekeeper. He remains loyal to Harry, Ron, and Hermione, though he is hurt when they skip his class. His role is more emotional, especially during events involving magical creatures.
Filius Flitwick - Charms Professor and Head of Ravenclaw. He maintains a supporting role, but is respected for his magical abilities and affable nature.
Pomona Sprout - Herbology professor and head of Hufflepuff. She has a minor role, but remains a trusted and dedicated figure to her students.

Lord Voldemort embarrasses both the wizarding and Muggle worlds by kidnapping wandmaker Garrick Ollivander from Diagon Alley and destroying the Millennium Bridge. The Malfoy family is disgraced when Lucius is arrested and sent to Azkaban for involvement with Death Eaters. Voldemort instead chooses Draco to carry out a secret mission at Hogwarts. Draco's mother, Narcissa, and his aunt Bellatrix Lestrange seek help from Severus Snape, who claims to have been acting as a mole within the Order of the Phoenix the entire time. Snape swears an Unbreakable Vow with Narcissa to protect Draco and carry out the task if Draco fails.

Harry Potter, now 16, accompanies Albus Dumbledore from Surbiton to the village of Budleigh Babberton to visit the former Potions professor Horace Slughorn. Slughorn, who has been in hiding the entire time, agrees to return to Hogwarts to teach.
