The Lancia Appia is a passenger car introduced in 1953 by Italian car manufacturer Lancia as a replacement for the Ardea, and which remained in production for ten years. The Appia was the last in a long line of Lancia production cars dating back to the Lancia Lambda to use sliding pillar front suspension. All three series produced had a 1089cc Lancia V4 engine.

Lancia is an Italian car manufacturer and a subsidiary of Stellantis Europe, which is currently a Stellantis division. The present legal entity of Lancia was formed in January 2007 when its corporate parent reorganised its businesses, but its history is traced back to Lancia & C., a manufacturing concern founded in 1906 in Torino by Vincenzo Lancia (1881–1937) and Claudio Fogolin. It became part of Fiat in 1969.
