São Jacinto Airfield, officially designated Aveiro Municipal Aerodrome (Portuguese: Aeródromo Municipal de Aveiro), is an aerodrome near the city of Aveiro in Portugal. It is located on a peninsula, between the Atlantic Ocean and the Vouga River estuary, in the parish of São Jacinto, near to the harbour of Aveiro, as well as the Costa de Prata (Silver Coast) beaches. It has a single runway in the 17/35 direction and a relatively large apron and has been operated in the past by all branches of the Portuguese Armed Forces. It is home to an air club, Aeroclube de Aveiro, but is currently closed to civilian traffic due to lack of certification.
