Will update as I become aware of more, feel free to chime in with some! Must be bunny-centric. If a bunny is an important side character but not the main thing, it doesn't go here; for example, I won't add Looney Tunes in general, but Looney Tunes things centered specifically on Bugs Bunny have made it on the list. Bunny bunnies included, bunny girls or bunny-people of any gender really (think human-with-bunny-ears-and-tail) excluded. Humans in bunny suits also excluded, so no Super Bunny Man.
Books
Bunnicula series

The Velveteen Rabbit
Watership Down
Movies
Hop
Night of the Lepus, also known as Rabbits; derivative of the book The Year of the Angry Rabbit (whose % rabbit vs political commentary is unknown, unlike the movie which Wikipedia says is horror with rabbits as the monster and no politics shows up in the summary)
