In the seventh and final book, Hermione is very valuable in Harry's quest to destroy Voldemort's remaining Horcruxes. Before leaving on the quest, she helps ensure the safety of her parents by placing a memory charm on them, making them think they are Wendell and Monica Wilkins, whose lifetime ambition is to move to Australia. She inherits Dumbledore's personal copy of The Tales of Beedle the Bard, which allows her to decipher some of the secrets of the Deathly Hallows. Hermione's spell saves her and Harry from Lord Voldemort and his snake Nagini in Godric's Hollow, although the ricochet snaps Harry's wand. When she, Ron, and Harry are captured by Snatchers, who are on the hunt for Muggle-borns under the Ministry's orders, Hermione disguises Harry by temporarily disfiguring his face with a Stinging Hex. She also attempts to pass herself off as former Hogwarts student Penelope Clearwater and a half-blood to avoid persecution, but is later recognised and taken to Malfoy Manor. Because of Hermione's Muggle-born status, Bellatrix Lestrange tortures her with the Cruciatus Curse in an attempt to extract information on how Hermione, Harry, and Ron came to possess Godric Gryffindor's sword (which was supposed to be safe in the Lestranges' vault in Gringotts). Even under the torture of the Cruciatus Curse, Hermione is able to use her quick thinking to lie to Bellatrix that the sword is a fake. When the others are able to escape their cell, Bellatrix threatens to slit Hermione's throat. Hermione, Harry, Ron and the other prisoners being held in Malfoy Manor are eventually rescued by Dobby.

Hermione later uses Polyjuice Potion to impersonate Bellatrix when the trio attempt to steal Hufflepuff's cup from Gringotts. She, Harry and Ron join Dumbledore's Army in the Battle of Hogwarts, during which Hermione destroys Hufflepuff's cup in the Chamber of Secrets with a basilisk fang, eliminating another Horcrux. Hermione and Ron also share their first kiss in the midst of the battle. In the final battle in the Great Hall, Hermione fights Bellatrix with the help of Ginny Weasley and Luna Lovegood. However, the three of them are unable to defeat Bellatrix, and stop fighting her once Molly Weasley orders them to back off. ron and hermione deathly hallows

Ron agrees to go with Harry and Hermione on the quest to destroy all of Voldemort's Horcruxes. Worried that the Ministry, now taken over by Voldemort will learn he is with Potter on a quest, Ron dresses the family ghoul up in pyjamas and spreads the story he is ill with "spattergroit," a type of highly contagious magical illness. Ron disguises himself as Reginald Cattermole as the trio attempts to find the locket Horcrux in the possession of Dolores Umbridge. ron and hermione deathly hallows

Harry decides he wants someone to wear the Horcrux at all time, fearing it might be lost or stolen. This has a much more profound effect on Ron than it seems to have on Hermione or Harry. Ron ends up lashing out in frustration at the lack of comforts and a concrete plan, eventually leaving his friends behind. Distressed over his absence, Harry and Hermione do not even mention his name during the time that he is gone. However, when they finally mention his name, Ron, who had immediately regretted his decision to leave but was captured by Snatchers and then could not return due to Hermione's anti-Death Eater enchantments, was lead to Harry's location by unknown magic within the Deluminator he inherited from Dumbledore. Ron dramatically returns by saving Harry from drowning when Harry is attempting to recover Godric Gryffindor's sword from an icy pool. Harry, a sudden believer in the fate created by his return, immediately forgives Ron and insists it must be Ron who uses the sword to destroy Slytherin's locket. However, the portion of Voldemort's soul inside it plays on Ron's insecurities by revealing that he thinks he is "least loved by a mother who craved a daughter", then by showing him a Harry who tells him that he was happier without him and a Hermione that does not return his affections and is involved instead with Harry. Ron summons his courage and finally breaks through the spell, destroying the locket, but is visibly shaken until Harry tells him that he thinks of Hermione as a sister and a friend, nothing more.ron and hermione deathly hallows

The trio are eventually captured by Snatchers, and Bellatrix Lestrange tortures Hermione with the Cruciatus Curse for information. This sends Ron into a panic, and he continually screams and fights with all his effort to save her, despite Harry's instruction that he calm down and think of a better plan. The trio and some other prisoners are rescued by Dobby, but the house-elf is killed by Bellatrix during the escape. Eventually, the trio returns to Hogwarts, hoping to find the last unknown Horcrux shown in Harry's vision. Having lost the Sword of Gryffindor to Griphook the goblin, Ron gets an idea to procure more Basilisk fangs and manages to speak enough Parseltongue to open the Chamber of Secrets, where Hermione destroys the Horcrux in Helga Hufflepuff's cup. He begins to worry about the fate of Hogwarts' elves. Upon hearing this, Hermione drops the basilisk fangs she was carrying and kisses him for the first time. After this, he looks as if he has been hit by a bludger. He also takes part in the Battle of Hogwarts, witnessing the death of his brother Fred, and teams up with Neville to defeat Fenrir Greyback. ron and hermione deathly hallows
