Bellanna

Bellanna is the femslash ship between Anna and Belle from the Once Upon A Time and Disney fandoms.

Canon
Anna comes across Belle at Oaken's trading post, where they got on after Anna learns that Belle wishes to find the Rock Trolls and because she knows where they are, and is also making her way to their valley for her own agenda; she tells Belle that she'll take her to them.

Fanon
While the ship is commonly focused on OUaT's version of the two, there are fans who use ship and its commonly used title with Disney's versions of them within the Disney Princess part of the Disney fandom, since the ABC television series has its own versions of the Disney characters and has a few traits from its series; and it being the live-action show that helped to trigger the ship or had helped to make it notable in both fandoms.

Because Ralph Breaks the Interest is a canon Disney crossover that has a version of the two know each other, like their once counterparts do in the Once Upon A Time series, fans of the Disney side of the ship sometimes have Belle and Anna in the modern, style clothes that the netizen versions of them wear in the film.
