Beiriz is a suburban area in Póvoa de Varzim, Portugal. Beiriz has origins in a medieval rural place known as Villa Viarizi as it is known by a document from 1044. The parish is very old, and it is known to exist from at least from this century onwards. It was a (religious) parish in Barcelos until 1836 when it became a civil unit and was transferred to Vila do Conde. Póvoa de Varzim and Vila do Conde made parish transfers in 1853, and Beiriz was made part of Póvoa de Varzim since then.
