Holland is a region and former province on the western coast of the Netherlands. The name Holland is also frequently used informally to refer to the whole of the country of the Netherlands. This usage is commonly accepted in other countries, and not entirely uncommon among the Dutch themselves. However, some in the Netherlands, particularly in other regions of the country, may find it undesirable or misrepresentative.

The area of the former County of Holland roughly coincides with the two current Dutch provinces of North Holland and South Holland, which together include the Netherlands’ three largest cities: the de jure capital city of Amsterdam; Rotterdam, home of Europe’s largest port; and the seat of government of The Hague.
