A [[window]] covering, usually wooden, consisting of solid or louvered panels that provide security, protect against weather, and/or control the amount of sunlight that enters a room. Shutters may be mounted on the inside or outside of a window, and they may be fixed or hinged. Some shutters are purely aesthetic in design and may not cover the windows at all.

Contrast with [[window blinds]], which hang freely instead of being set in a frame.

Not to be confused with [[window shadow]], which are shadows created by a window.
