St. Mungo's Hospital for Magical Maladies and Injuries is the primary, and likely only, wizarding hospital in Great Britain. It was founded in the 1600s by the famous Healer Mungo Bonham, whose portrait hangs in the hospital. The hospital's emblem is a crossed wand and bone. To maintain secrecy from Muggles, the hospital is concealed behind the facade of a shabby-looking, red-brick department store in London called Purge and Dowse, Ltd.. The exterior is deliberately uninviting, with dusty windows displaying broken mannequins in outdated fashions. Entry is gained by approaching a specific female mannequin in the window and speaking to it. The visitor then simply walks through the display glass, which ripples like water, to arrive in the hospital's reception area. The reception is a crowded and chaotic hall, often filled with witches and wizards suffering from various comical or serious magical afflictions. A Welcome Witch sits at an enquiry desk to direct patients and visitors. The atmosphere is frantic, with sounds of screams, bangs, and strange magical occurrences. The walls are lined with portraits of notable Healers, including one of Urquhart Rackharrow, the inventor of the Entrail-expelling Curse.

St. Mungo's is a key location in Harry Potter and the Order of the Phoenix. Following his attack by Nagini in the Department of Mysteries, Arthur Weasley is brought to St. Mungo's for treatment. Harry Potter and the Weasley family visit him on Christmas Day, providing Harry with his first detailed look inside the wizarding world's primary medical institution. During these visits, the group overhears conversations about Broderick Bode's mysterious strangulation by a potted Devil's Snare, hinting at the Death Eaters' attempts to retrieve the prophecy. Most significantly, it is here that Harry, Ron Weasley, Hermione Granger, and Ginny Weasley encounter Neville Longbottom visiting his parents, Frank Longbottom and Alice Longbottom. They are permanent residents of the Janus Thickey Ward for long-term spell damage, having been tortured into insanity by Bellatrix Lestrange and other Death Eaters. This encounter is a pivotal moment for understanding Neville's character and the true cost of the First Wizarding War. The group also finds their former Defence Against the Dark Arts professor, Gilderoy Lockhart, in the same ward, still suffering from amnesia caused by a backfired Memory Charm. The hospital is mentioned on other occasions:

• Minerva McGonagall is sent there after being hit by four simultaneous Stunning Spells while defending Rubeus Hagrid from Dolores Umbridge.
• Katie Bell is treated at St. Mungo's for several months after being cursed by a cursed Opal Necklace.
• Nymphadora Tonks is taken to the hospital after being injured during the Battle of the Department of Mysteries.

St. Mungo's is organized by floor, with each floor dedicated to a specific category of magical malady.

• Ground Floor: Artefact Accidents: This ward handles injuries from backfiring wands, cauldron explosions, and broomstick crashes.
• First Floor: Creature-Induced Injuries: This floor is for treating bites, stings, burns, and other injuries caused by magical creatures. Arthur Weasley was treated here in the “Dangerous” Dai Llewellyn Ward.
• Second Floor: Magical Bugs: This ward handles contagious magical illnesses such as Dragon Pox, Scrofungulus, and Vanishing Sickness.
• Third Floor: Potion and Plant Poisoning: This floor treats patients suffering from rashes, regurgitation, and other afflictions caused by potions or magical plants.
• Fourth Floor: Spell Damage: Housed in the Janus Thickey Ward, this area is for patients with permanent or long-term damage from severe jinxes, hexes, or incorrectly applied charms. Gilderoy Lockhart, Frank Longbottom, Alice Longbottom, and Broderick Bode were all patients here.
• Fifth Floor: Visitor's Tearoom and Hospital Shop: A space for visitors to relax and purchase gifts or refreshments.

• Etymology: The hospital is named after Saint Mungo, the patron saint of Glasgow, Scotland. Saint Mungo was a 6th-century Christian missionary who was said to have performed four miracles, one of which involved restoring life to a pet robin, linking him to healing and restoration.
• Founder: The founder, Mungo Bonham, is featured on a Chocolate Frog Card which confirms he was a famous Healer who founded St. Mungo's Hospital. (Pottermore)
• In the film adaptation of Harry Potter and the Order of the Phoenix, the entrance to St. Mungo's through the mannequin in the shop window is shown, but the interior wards and the encounter with Neville Longbottom's parents are omitted. (film)
