St. Andrew's Day is the feast of Saint Andrew, celebrated on 30 November each year. Saint Andrew is the patron saint of Scotland and St. Andrew's Day is Scotland's official national day, although Burns' Night is more widely observed. In 2006, the Scottish Parliament designated the Day as an official bank holiday.

In Germany it is celebrated as Andreasnacht (German: St Andrew's Night), in Austria with the custom of Andreasgebet (St Andrew's Prayer) and in Poland as Andrzejki ("Andrews").
