Augusta Longbottom is the mother of the Auror Frank Longbottom and grandmother of Neville Longbottom. After both Neville's parents were tortured into insanity by Death Eaters she was the one to raise him.
 Character development
In her youth, Augusta attended Hogwarts School of Witchcraft and Wizardry in which she was known to fail her O.W.L in Charms.  After Lord Voldemort's defeat in 1981, Augusta's son Frank Longbottom and his wife Alice Longbottom were tortured by death eaters, driving them into madness, prompting carers to send them to St Mungo's. They left behind their son Neville Longbottom and he was soon put into Augusta's care. Augusta and other relatives initially thought that Neville was a squib and Augusta was greatly disappointed in him. She realised that he was infact a wizard when he was thrown out the window and bounced down the road.

 Third book
Harry Potter spots Neville and Augusta in Diagon Alley. He is somewhat loath to approach them, having recently pretended to be called Neville Longbottom when temporarily on the run from the Ministry of Magic for blowing up his aunt. Also Augusta was at that moment telling Neville off for losing his booklist. Harry really hoped that she would never know he had pretended to be her grandson.
Neville had chosen to take Divination as an optional O.W.L. subject and started his first lesson that year. His teacher, Professor Trelawney, began the lesson with an impressive array of predictions about her students. At one point she turned to Neville and asked him if his grandmother was well. After he replied that he thought so, she darkly proclaims that he shouldn't be so sure of that. However we never hear any news that she was unwell.
Also that year the new Defence Against the Dark Arts professor, Remus Lupin, chose Neville to help him demonstrate a new spell - Riddikulus - and how to defeat a Boggart. To defeat it Neville needed to turn his worst fear into something funny in order to make him laugh. His worst fear turned out to be Potions teacher Severus Snape. Lupin suggests that to make him look like something amusing Neville could imagine Snape in his grandmother's clothes. Neville was successful, and the class was treated to the normally imposing Professor Snape wearing a long green dress with lace, a hat with a stuffed vulture on top and a large red handbag (Augusta's typical attire). The whole school seemed to learn about this and Severus Snape was not best pleased. He took it out on Neville during lessons and was more angry than ever with Lupin.
The school had been buzzing with the news after escaped convict Sirius Black had attempted to enter the Gryffindor common room at Hallowe'en, where he was stopped only by the Fat Lady for not knowing the password. The security was increased to prevent him coming back. However Sirius did later manage to enter again. Neville had persuaded the new portrait for Gryffindor tower, Sir Cadogan, to tell him the week's passwords in advance so that he could write them down and remember. Sirius had managed to get hold of these thanks to Crookshanks, however to all appearances Neville had simply left them lying around. Augusta was furious with Neville when she found out, and sent him a Howler, the worst mail a student can possibly get.
 Fourth book
Neville had really wanted to go to the Quidditch World Cup which was being held in Britain. Unfortunately Augusta did not want to go, so she wouldn't buy the tickets. He jealously listened to the others' stories about it and was wowed by the merchandise they had bought there.
When later that day the fact that Hogwarts would be hosting the long unplayed Triwizard Tournament, but that those under the age of 17 would not be able to take part, Neville thought that his gran would want him to have a go. He gloomily recollected that she was often saying he needed to 'uphold the family honour'. He, however, didn't think he'd learnt enough.
After Harry Potter accidentally views Albus Dumbledore's memories in his Pensieve, an object Harry was unfamiliar with, Hary heard about the fate of Neville's parents for the first time. When Dumbledore allows Harry to question him about the Pensieve he asks Harry whether Neville has ever told him why he was brought up by Augusta. This is the first time Harry has realised he never knew why. Dumbledore explains that she brought Neville up after his parents were tortured into insanity, and that they both visit Frank and Alice during the holidays. Harry is horrified to learn this and wonders how he had never asked before. 
 Fifth book
In this book, Augusta appears again. After Harry Potter has the dream in which he sees Arthur Weasley being attacked by a snake, Harry goes along with the Weasley family to London to visit Mr. Weasley in St. Mungo's. While they are there, Harry, Ron, Hermione, and Ginny, leave Mr. Weasley's ward and go wandering to find a cup of tea. As they are walking they run into Gilderoy Lockhart who is in St. Mungo's for memory issues described in Harry Potter and the Chamber of Secrets. Lockhart happens to be in the same ward as Neville's parents, and Augusta and Neville are in the ward visiting. Augusta is surprised to hear that Neville hasn't told his friends about his parents and tells Neville that he should be proud and not ashamed by his parents' fate.
 Sixth book
During the summer holidays of 1996 following Neville's venture into the Department of Mysteries, Augusta was interviewed in the Daily Prophet about her opinion on the new safety measures at Hogwarts. During this interview she managed to mention Neville's friendship with Harry and that he had fought the Death Eaters with him.
On the Hogwarts Express when Harry brings up how the Daily Prophet had managed to somehow learn about the events at the Hall of Prophecy Neville says that he thought his grandmother would be annoyed by the publicity, but instead was pleased. She said that he was at last living up to his father's reputation and bought Neville a new wand from Ollivander's to replace his old broken one.
When the time comes for the students to pick their N.E.W.T.s and be given their timetables, Minerva McGonagall has some difficulty helping Neville with his. She wont let him continue to take Transfiguration after getting an "Acceptable" in his O.W.L., and wonders why he even wants to carry one when he doesn't like the subject. He replies that his grandmother wants him to take the subject.
"It's high time your grandmother learned to be proud of the grandson she's got, rather than the one she thinks she ought to have - particularly after what happened in the Ministry." - Minerva McGonagall
McGonagall suggests Charms as an alternative, but Neville replies that his grandmother thinks it's a soft option. McGonagall insists that he takes the subject and resolves to write to his grandmother, revealing as she does that Augusta failed her own Charms O.W.L., to Neville's delighted surprise.
 Final book
In 1997, Death Eaters took over the Ministry of Magic as well as Hogwarts, where Neville still studied. Neville was one of the many students who stood up to the death eaters and he was constantly punished. Wanting to silence Neville, the Death Eaters sent auror, John Dawlish to capture Augusta so that Neville would behave. Unfortunately for John, Augusta put up a fight which left Mr Dawlish in St Mungo's. She later returned to Hogwarts to participate in The Battle of Hogwarts and fought alongside her grandson, who she was now very proud of.
