The Little Belt is a strait between the Danish island of Funen and the Jutland Peninsula.

The belt is about 50km long and 800m to 28 km wide, the maximum depth is approximately 75m. Numerous small islands are located within the belt.

Two bridges cross the belt, the Old Lille Belt bridge and the New Little Belt bridge; also the two Lille Belt overhead powerline crossings.

The belt is used in the 1841 written German national anthem, the Deutschlandlied, to define the northern limit of the then German speaking world.
