Tønder (Danish pronunciation: [ˈtsʰønˀɐ]; German: Tondern [ˈtɔndɐn]) is a town in the Region of Southern Denmark.

In spite of the improvement in cross-border traffic, the location of the town continued to hamper industrial growth through the late 20th century, although some companies did set up businesses.

[5] Every August, the Tønder Festival offers visitors a wide variety of traditional and modern folk music.

The Scouts of Tønder are twinned with Hemyock, in Devon, England, and make exchange trips between the countries every few years.

This is due in part to Denmark's liberal marriage laws, compared with those in nearby Germany which requires a minimum of three months' residence and where the ceremony has to be in German.

However, in Denmark, the marriage formalities can be completed in around a week, with fewer documents required and the vows may be taken in languages other than Danish.
