The name Bean is a boy's name of English origin. Bean and is often added to user-created lists like Nature Names Off the Beaten Track and discussed in our forums with posts like "Generation CAF (14)".
From the experts:
The unisex word name Bean, distant cousin of the infamous Apple, was used for the name of a child of mysterious gender in Louise Penny's novel "A Rule Against Murder." While we can imagine Bean as a cute nickname for a yet-unnamed and unborn baby, we don't recommend it for real life.
