Denmark is a Nordic country located in Northern Europe. It is unique in that it does not share land borders with many countries; in fact, Denmark is bordered only by one country: Germany. This border lies to the south of Denmark, where the Jutland Peninsula connects with Germany.
To the north, Denmark is separated from Sweden by the Øresund Strait, which is crossed by the famous Øresund Bridge linking the two countries. While Sweden is not a direct neighbor by land, it is very close by water. To the east, Denmark is surrounded by the Baltic Sea, and to the west, it is bordered by the North Sea.
So, in summary, Denmark shares a land border only with Germany but has close maritime neighbors, including Sweden and Norway across the seas.
