Albairate (Lombard: Bairaa or Albairaa [(al)bajˈraː]) is a comune (municipality) in the Metropolitan City of Milan in the Italian region Lombardy, located about 20 kilometres (12 mi) southwest of Milan.

Albairate borders the following municipalities: Corbetta, Cisliano, Cassinetta di Lugagnano, Gaggiano, Abbiategrasso, and Vermezzo.

During the 13th century, the process of the town being released from vassalage and instituted as a proper rural comune took place.

It later passed, along with the rest of Milanese territory, under the rule of the Visconti and then the Sforza.

On April 5, 1570, Cardinal Carlo Borromeo, Archbishop of Milan, paid a visit to Albairate stimulating a spiritual renewal of the parish and starting the social development of the country.
