Mrs. Lupin is the mother of Remus Lupin. Along with her husband, she worried that her son would not be able to attend Hogwarts School of Witchcraft and Wizardry, due to his lycanthropy, but Albus Dumbledore made a special provision for him.

J.K. Rowling revealed that Remus Lupin was half-blooded in an interview, and, from this, it can be inferred that at least one of his parents was magical. Mr. Lupin was likely a wizard, as he had contact with Fenrir Greyback at one point, which can either imply that Mrs. Lupin was a Muggle, or that one — or even both — of the Lupin couple was Muggle-born/half-blooded. However, Remus' statement that both of his parents "tried everything" to cure his lycanthropy suggests she may have been witch, as a Muggle probably wouldn't have had the power to treat a wizarding condition.
