A porte-cochere is the architectural term for a porch or portico-like structure at the entrance to a building, through which it is possible for a horse and carriage or motor vehicle to pass, in order for the occupants to alight under cover, protected from the weather.

The porte-cochere was a feature of many late 18th and 19th-century mansions and public buildings. Well-known examples are at Buckingham Palace in London and the White House in Washington.
