Hermione Granger is another of the main characters in the Harry Potter stories. She meets Harry and Ron on the train to Hogwarts in the first book and after an initial dislike they all become best friends.
Hermione is an integral part of the successes of the trio as she is the most academic and is able to help out with researching and planning as well as being superior at potion making and spell casting (though not as naturally talented as Harry - harder working).
