Zealand, (Danish:Sjælland; pronounced [ˈɕɛˌlanˀ]), is the largest (7,031 km) and most populated island in Denmark with a population just under 2.5 million, representing about 45% of the country's total population.

It is the 96th-largest island in the world by area and the 35th most populous. It is connected to Funen by the Great Belt Bridge, to Lolland, Falster (and Germany from 2021) by the Storstrøm Bridge and the Farø Bridges. Zealand is also linked to Amager by five bridges. Zealand is linked indirectly, through intervening islands by a series of bridges and tunnels, to southern Sweden.
