Soffit (from French "soffite", Italian "soffitto", formed as a ceiling; directly from "suffictus" for "suffixus", Latin "suffigere", to fix underneath), in architecture, describes the underside of any construction element. Examples of soffits include:
* the underside of an arch or architrave (whether supported by piers or columns),
* the underside of a flight of stairs, under the classical entablature,
* the underside of a projecting cornice, or
* the underside of a ceiling to fill the space above the kitchen cabinets, at the corner of the ceiling and wall.

In popular use, "soffit" most often refers to the material forming a ceiling from the top of an exterior house wall to the outer edge of the roof, i.e., bridging the gap between a home's siding and the roofline, otherwise known as the eaves.

Soffit exposure profile (from wall to fascia) on a buildings' exterior can vary from a few centimetres (2-3 inches) to well beyond a meter (3 feet) depending on construction. It can be non-ventilated or ventilated for cooling non livable attic space.
