The Channel Ports are seaports in southern England and northern France, which allow for short crossings of the English Channel. There is no formal definition, but there is a general understanding of the term. Some ferry companies divide their routes into "short" and "long" crossings. The broadest definition might be from Plymouth east to Kent and from Roscoff to Zeebrugge although a tighter definition would exclude ports west of Newhaven and Dieppe. A historic group of such ports is the Cinque Ports of south-east England, most of which have ceased to be commercial ports.[1]
