Portuguese Sign language (Portuguese: Língua gestual portuguesa) is a sign language used mainly by deaf people in Portugal.

It is recognized in the present Constitution of Portugal.[2] It was significantly influenced by Swedish Sign Language, through a school for the Deaf that was established in Lisbon by Swedish educator Pär Aron Borg.[3][4]
