Dover () is a major ferry port in Kent, South East England. It faces France across the Strait of Dover, the narrowest part of the English Channel, and lies south-east of Canterbury and east of Maidstone. The town is the administrative centre of the Dover District and home of the Dover Calais ferry through the Port of Dover. The surrounding chalk cliffs are known as the White Cliffs of Dover.
Archaeological finds have revealed that the area has always been a focus for peoples entering and leaving Britain. The name derives from the River Dour that flows through it.
The Port of Dover provides much of the town's employment, as does tourism.
