Santo Estêvão (pronounced as /pt/) is a former civil parish, located in the municipality of Alenquer, in western Portugal. In 2013, the parish merged into the new parish Alenquer (Santo Estêvão e Triana).[1] It covers 16.09 km² in area, with 5338 inhabitants as of 2001.[2] It was extinguished (aggregated) in 2013 as part of a national administrative reform, having been added to the parish of Triana to form a new parish called União das Freguesias de Alenquer (Santo Estêvão e Triana), of which it is the seat.[3]
