Siena–Ampugnano Airport (Italian: Aeroporto di Siena-Ampugnano) (IATA: SAY, ICAO: LIQS) was a small military airfield in Ampugnano, near Siena, in Tuscany, Italy. All employment has been terminated in 2014.

2008 the site has been proposed for a new international airport capable of handling 4 million passengers a year by 2020. Since 2003 the project has met widespread local opposition. Upon request about current status and future of the airport in November 2016 the Siena Comune confirmed by eMail: ″the airport of Siena is not operating″. As of January 2017, the field is mentioned as being operated by Sky Services. There are however indications of rather high rates, opposed to limited levels of service.
