49 free Sirius Black trivia questions with answers — literature quiz, new questions added Oct 2026.
Sirius Black is Harry Potter's godfather, the runaway heir of the House of Black, best man at James and Lily's wedding and the titular Prisoner of Azkaban. He is mentioned in the very first chapter of the series as the wizard who lent Hagrid a flying motorbike, spends twelve years wrongly imprisoned for Peter Pettigrew's crimes, becomes the first person to escape Azkaban under his own power, and dies at the Department of Mysteries at his cousin Bellatrix's hand. This quiz covers all of it: the constellation naming tradition, the Gryffindor sorting that broke with family habit, the Marauders and the Animagus dog called Padfoot, Uncle Alphard's inheritance, the fatal Secret-Keeper switch, Scabbers on the front of the Daily Prophet, Crookshanks and the Firebolt, the cave above Hogsmeade, Number 12 Grimmauld Place and Kreacher, the veil, the Resurrection Stone, and the family tree sold for £30,000 on Daniel Radcliffe's behalf. It also covers Gary Oldman, who took the part because he needed the money and did not know the character was going to die. Fifty questions, four options each, with a short explanation after every answer. Play on your phone or print it for a Harry Potter quiz night.

Q 01What is Sirius Black's relationship to Harry Potter?
Godfather
Godfather: James and Lily chose him when Harry was born. On the very night he proves his innocence to Harry, he asks whether Harry would like to leave the Dursleys and live with him.
Q 02In which book is Sirius first mentioned, as the lender of a flying motorbike?
Philosopher's Stone
Philosopher's Stone, sold as Sorcerer's Stone in the US: Hagrid names him in chapter one as the bike's owner. An early draft gave Sirius a whole scene there, cut down to that one mention.
Q 03Which code name does Sirius ask Harry, Ron and Hermione to use when they talk about him?
Snuffles
Snuffles is the name he asks for in Goblet of Fire, because he is still a wanted man and anyone at Hogwarts might overhear them. Nobody listening would connect so silly a pet name with a fugitive.
Q 04What of Sirius's dead mother still screams at visitors to the family home?
Her portrait
Her portrait is stuck fast to the hall wall, so the Order has to creep past it rather than set her off. She and her husband Orion were second cousins, both born Blacks.
Q 05What was the name of Sirius's younger brother?
Regulus
Regulus Arcturus Black is the R.A.B. of the fake locket. Sirius died thinking his brother had simply lost his nerve, never learning that he had turned on Voldemort and died for it.
Q 06Which of his three cousins was Sirius's favourite?
Andromeda Tonks
Andromeda Tonks broke with the family much as he did: she married Ted Tonks, a Muggle-born wizard, and their daughter Nymphadora grew up to join the Order of the Phoenix.
Q 07The Black family names its children after what?
Stars and constellations
Stars and constellations: his father was Orion and his grandfathers Arcturus and Pollux. The first Sirius Black died as a boy, and his brother, a future Hogwarts headmaster, gave the name to his own son; the runaway was the third.
Q 08Which Hogwarts house was Sirius sorted into, breaking with the rest of his family?
Gryffindor
Gryffindor, where almost every other Black had been a Slytherin. He rubbed it in at home by covering his bedroom walls with his house's banners, stuck on so firmly that his parents could never take them down.
Q 09Which enchanted object did Sirius and his three closest friends make while they were students at Hogwarts?
The Marauder's Map
The Marauder's Map shows everyone inside Hogwarts by name. Years later it shows Lupin a man who is supposed to be dead, Peter Pettigrew, which is how the truth about Sirius starts to come out.
Q 10Why did Sirius, James and Peter secretly become Animagi?
To keep a werewolf friend company
To keep a werewolf friend company: as animals they could safely stay beside Lupin at full moon. It took them the best part of three years to learn how, and none of them ever registered with the Ministry.
Q 11Whom does Sirius attack on Halloween for refusing to let him into a Hogwarts tower?
The Fat Lady
The Fat Lady: he slashes her canvas when she will not open up without the password. Her stand-in, Sir Cadogan, the only painting willing to take the job, later lets Sirius straight in because he reads out a stolen list of passwords.
Q 12What nickname do Sirius's closest school friends call him?
Padfoot
Padfoot comes from the shape he takes as an Animagus, as do Prongs and Wormtail. Only Moony is different: Lupin's name points to something he never chose.
Q 13What did Sirius's mother burn his name off when he ran away?
Tapestry
Tapestry: the Blacks' family tree was woven into one, and she burned off anyone who broke with their pure-blood creed. At sixteen he moved in with James Potter's parents, who treated him as a second son.
Q 21How did Sirius physically get out of his Azkaban cell?
He slipped through the bars as a thin dog
He slipped through the bars as a thin dog: years of prison had starved him gaunt enough to fit between them, and the Dementors could barely sense an animal's simpler mind going past.
Q 22Which omen of death does Harry mistake the dog-form Sirius for?
The Grim
The Grim is a giant spectral dog said to haunt churchyards, and Professor Trelawney also finds it in Harry's teacup. After that, every glimpse of the stray watching him looks like her prediction coming true.
Q 23Which cat befriends Sirius and helps him hunt the traitor Pettigrew?
Crookshanks
Q 14Which relative left Sirius a large inheritance that made him financially independent?
His Uncle Alphard
His Uncle Alphard, his mother's brother, left him enough gold to set up a home of his own at seventeen. From then on the runaway never needed anything from his parents again.
Q 15What role did Sirius play at James and Lily's wedding?
Best man
Best man, and barely out of school when he stood up beside James. That closeness is why, when the Potters were betrayed a few years later, he was the friend everyone blamed.
Q 16Which spell hid the Potters and required a Secret Keeper?
The Fidelius Charm
The Fidelius Charm seals a secret inside one living person. While that Secret Keeper stayed silent, Voldemort could have pressed his nose to the Potters' window and still not have found them.
Q 17Why did Sirius urge the Potters to make Pettigrew their Secret Keeper instead?
As a bluff to fool Voldemort
As a bluff to fool Voldemort: Sirius was the obvious choice and expected to be hunted, so he put forward a friend nobody would suspect. That friend was already Voldemort's spy inside the Order.
Q 18Which body part did Pettigrew leave behind when he framed Sirius for murder?
A finger
A finger, cut off by his own hand before he blew the street apart and fled into the sewer as a rat. With a crowd of witnesses to the blast, nobody thought to look for a living Pettigrew.
Q 19Who sent Sirius to Azkaban without a trial?
Barty Crouch Sr
Barty Crouch Sr, then head of magical law enforcement, had him locked up without a hearing. Sirius later said Crouch had become as ruthless and cruel as many of the Dark wizards he was hunting.
Q 20What did Sirius spot on the front page of the Daily Prophet that drove him to escape?
Scabbers on Ron Weasley's shoulder
Scabbers on Ron Weasley's shoulder, in a family photo: Sirius knew the rat at once as Pettigrew. The newspaper had been handed to him by the Minister for Magic himself, during an inspection of the prison.
Crookshanks, who is half-Kneazle, could tell at once that the big stray was no ordinary dog. He went on to steal a list of passwords from Neville so that Sirius could get into the castle.
Q 24What does Sirius anonymously send Harry for Christmas in his third year?
A Firebolt
A Firebolt, ordered in Harry's name but paid for out of Sirius's own Gringotts vault. McGonagall confiscated it on the spot, fearing the wanted man had sent it jinxed.
Q 25What does Sirius give Harry so they can talk in secret, a gift Harry leaves unopened until too late?
A two-way mirror
A two-way mirror, one of a pair he and James had used to talk when apart at school. Harry left the parcel unopened so as not to tempt Sirius out of hiding, and found it only after he had died.
Q 26What sentence is Sirius given after his capture at Hogwarts?
The Dementor's Kiss
The Dementor's Kiss sucks out the soul and leaves the body alive, a fate called worse than death. Harry and Hermione free him first, and he flies off on a hippogriff that had also been condemned.
Q 27Where does Sirius hide while near Hogsmeade in Goblet of Fire?
A cave in the hills
A cave in the hills, shared with Buckbeak, where he lived mostly on rats. An early draft was kinder: a dog-loving witch called Mopsy took the stray in, until she was cut from the book.
Q 28Which magazine claimed that Sirius was really Stubby Boardman, a retired pop singer?
The Quibbler
The Quibbler ran it as a scoop: its witness swore the man could not be the killer because he had been having dinner with her that night. The singer had quit after being hit on the ear by a turnip.
Q 29What is the address of the Black family home Sirius turns into Order headquarters?
Number 12 Grimmauld Place
Number 12 Grimmauld Place came to him as the last of the Blacks, and he handed the house he had once run away from to the Order. With a manhunt on, he then could not set foot outside it.
Q 30What is the name of the Black family house-elf Sirius mistreats?
Kreacher
Kreacher took a snapped 'get out' from Sirius as leave to quit the house altogether. He went straight to Narcissa Malfoy and began passing on whatever he could about his master.
