Hook of Holland is a town in the southwestern corner of Holland, hence the name; hoek means "corner" and was the word in use before the word kaap – "cape", from Portuguese cabo – became Dutch. The English translation using Hook is a false cognate of the Dutch Hoek, but has become commonplace. It is located at the mouth of the New Waterway shipping canal into the North Sea. The town is administered as a district of the municipality of Rotterdam. Its district covers an area of 16.7 km2, of which 13.92 km2 is land. On 1 January 1999 it had an estimated population of 9,400.

Rotterdam is the second-largest city in the Netherlands after the national capital of Amsterdam. It is in the province of South Holland, part of the North Sea mouth of the Rhine–Meuse–Scheldt delta, via the "New Meuse" inland shipping channel, dug to connect to the Meuse at first and now to the Rhine.
