Sinterklaas or Sint-Nicolaas is a legendary figure based on Saint Nicholas, patron saint of children. Other Dutch names for the figure include De Sint, De Goede Sint and De Goedheiligman. Many descendants and cognates of "Sinterklaas" or "Saint Nicholas" in other languages are also used in the Low Countries, nearby regions, and former Dutch colonies.

Zwarte Piet, also known in English by the translated name Black Pete, is the companion of Saint Nicholas in the folklore of the Low Countries. Traditionally, Zwarte Piet serves as an assistant to the saint and distributes sweets and gifts to well-behaved children.
