A baseboard is a piece of wood molding that runs along the bottom of a wall. Where the bottom of a baseboard ends, the floor begins.

A baseboard is a decorative architectural element you'll see in most homes, usually a wide board that's painted to match the trim color of the room. A baseboard is useful for hiding any unevenness in the joint where the wall meets the floor. In Britain, this is called skirting. The word baseboard, from the mid-1800s, combines base, "bottom," and board, or "plank."
