Augusta Longbottom (fl. 1947-1998) was a pure-blood witch and member of the Longbottom family by marriage. She was the mother of famous Auror Frank Longbottom, mother-in-law to Auror Alice Longbottom, and grandmother to Neville Longbottom.
Little is known about Augusta's early life. In her school years, Augusta failed her Charms O.W.L., according to Professor McGonagall, causing her to later label it a "soft option." It is likely that Augusta went to school with Professor McGonagall and attended under Headmaster Dippet. 
Raising her grandson
During the First Wizarding War, Augusta's son Frank was both an Auror and a member of the Order of the Phoenix, as was his wife Alice. The highly respected couple survived the war, but shortly after Lord Voldemort's defeat in 1981, they were attacked by Death Eaters who tortured them into insanity with the Cruciatus Curse. The couple had to be institutionalized, and their infant son Neville was placed into Augusta's care.
Augusta was clearly strict with her grandson, who she initially feared was a Squib. Even after Neville proved to be a wizard, his grandmother was stern and demanding of him, sending him Howlers when his behaviour displeased her and pressuring him to uphold the "family honour." She often took Neville to visit his incapacitated parents at St. Mungo's, stating that he should be proud of their sacrifice.
Second Wizarding War
In 1995, Augusta supported Harry Potter and Albus Dumbledore when they claimed that Lord Voldemort had returned to power, as did Neville. Her support even led her to stop subscribing to the Daily Prophet, due to the newspaper's vicious smear campaign against Harry and Dumbledore. When she found out that Neville has not told anyone of his parents' condition, she became angry at him for thinking he was ashamed and told Harry Potter, Ronald Weasley, Hermione Granger, and Ginny Weasley about it. Sternness soon turned to pride, as she finally became proud of Neville after his involvement in the Battle of the Department of Mysteries.
In 1997, after Death Eaters had taken control of the Ministry of Magic, Neville was one of the leaders of the student rebellion against Alecto and Amycus Carrow at Hogwarts. In an attempt to force Neville to be more cooperative, Auror John Dawlish was ordered to capture Augusta and take her hostage to ensure Neville's behaviour. Augusta, however, put up a fight, which Dawlish wasn't expecting; according to Neville, she put Dawlish in St. Mungo's. After this, Augusta went on the run.
She later re-emerged at the Battle of Hogwarts to assist Neville when he called everyone to arms against the Death Eater army. She expressed great pride in her grandson for following in his parents' footsteps. Augusta fought during the battle and survived.
Augusta Longbottom was described as a formidable looking witch. She was tall, thin and bony. She commonly wore a hat with a stuffed vulture on it and carried a bright red handbag.
Personality and traits
- "That Harry Potter's got more backbone than the whole Ministry of Magic put together!"
- —Augusta's views on the Ministry
Augusta Longbottom was a severe woman who frequently claimed that her grandson, Neville, lacked the talents that his parents had possessed. She was angry when she realised Neville had never told anyone about why he lived with her, thinking that he was ashamed of his parents. Nevertheless, Augusta grew proud of her grandson after discovering how dedicated he was to defeating Lord Voldemort. She was civil towards Harry Potter, Ronald Weasley, and Hermione Granger when she met them in St Mungo's.
Magical abilities and skills
- Duelling: Despite her age, Augusta Longbottom was a skilled duellist and the Death Eaters underestimated her duelling abilities, as she caused enough injury to John Dawlish, a highly trained and skilled Auror, to result in him to be sent to St. Mungo's Hospital for Magical Maladies and Injuries. She also participated in and survived the Battle of Hogwarts.
- Transfiguration: As she disliked her grandson taking Charms, a class she failed, it is likely she wishes him to take the subjects she did. She wanted Neville to take Transfiguration, implying she did well in it.
During the early years of Neville's life, Augusta often thought that Neville was a Squib and was afraid he would not get into Hogwarts. She was extremely proud when he did but it was apparent that Neville and his grandmother were not very close as Augusta was seen reprimanding her grandson. Augusta also sent Neville a Howler and pushed Neville to be like his parents by doing well in school, especially in Transfiguration, a class Neville hated. In later years, she became proud of Neville as she realised how excellent a wizard and person he was. She was shown commenting in the Daily Prophet about his powers and during the Battle of Hogwarts, she was proud to fight alongside him.
It is unknown what her relationship with Frank and Alice was before they were tortured, but it must have been fairly close as Augusta was chosen to raise their infant son after they were no longer able to. After the attack, Mrs Longbottom seemed to love her son and daughter-in-law, often taking Neville to visit them at St. Mungo's. However, at times, she seemed to tire of providing for them, as she sounded weary when speaking to Alice and advised Neville to throw away a gum wrapper Alice gave him. However, it is assumed that she still cared for them as she obviously respected them and says numerous times that she wants Neville to be more like them.
Augusta and Madam Marchbanks were described as close friends by Neville Longbottom. Griselda had come for dinner at Mrs Longbottom's many times.
It is implied that Minerva McGonagall attended school and was friends with Augusta Longbottom; McGonagall knows that Augusta failed her Charms O.W.L. and said she would 'drop her a line', implying that they are in contact with each other.
Augusta is a Latin name and the feminine form of Augustus, meaning "great" or "venerable," derived from the Latin verb augere, "to increase."  Augustus was the name given to the first emperor of Rome, and subsequently Augusta was sometimes used as a title for empresses of the Roman and Byzantine empires.
Behind the scenes
- The 2006 short film The Queen's Handbag includes a reference to Neville's grandfather, and describes a joke he played on Augusta in 1947 involving her handbag and a fanged gerbil, which led her to keep a mousetrap in her bag thereafter.
- Augusta was played by Leila Hoffman in the film adaptation of Harry Potter and the Philosopher's Stone, as she was faintly seen escorting Neville to the Hogwarts Express. 
- Ninette Finch was cast as Augusta in Harry Potter and the Deathly Hallows: Part 2. Her scenes were cut, however it appears she can be seen in the background of some battle sequences.
