Zealand at 7,031 km2, is the largest and most populated island in Denmark with a population of 2,267,659 (39% of Denmark's total as of January 2016).

It is the 13th-largest island in Europe by area and the 4th most populous. It is connected to Funen by the Great Belt Fixed Link, to Lolland, Falster. It will also be connected to Germany from 2028, by the Storstrøm Bridge and the Farø Bridges. Zealand is also linked to Amager by several bridges. Zealand is linked indirectly, through intervening islands by a series of bridges and tunnels, to southern Sweden.

Copenhagen, the capital of Denmark, is located partly on the eastern shore of Zealand and partly on the island of Amager. Other cities on Zealand include Roskilde, Hillerød, Næstved and Helsingør. The island is not connected historically to the Pacific nation of New Zealand, which is named after the Dutch province of Zeeland.
