I don't remember any references to Neville being left-handed in the books. Is this based on the films? Should we consider scenes in the films in which a character is shown writing, using a wand, etc. with a specific hand as canonical evidence of their handedness?

I've gotta say, I'm really not sold on the necessity of having an article for this. Sexual orientation was one thing, as Dumbledore's outing caused enough controversy that Rowling addressed the issue in no less than three seperate interviews, but this? - Nick O'Demus 05:32, April 24, 2011 (UTC)
It's definitely a very minor factor in canon, probably only of interest to hardcore trivia enthusiasts, or creators of fan works who want to get every single detail correct. But there is the apparent difference in how Muggles and wizards define handedness, and this article is a handy convenient place to put a list of known left- and right-handed characters, similar to how there's a list of spectacle-wearers at Spectacles.
