NEWHAVEN, a town of the county of Sussex, and the hundred of Holmstrough, sixty miles distant from London. It stands at the mouth of the river Ouse, and is the port of Lewes, where the custom-house is established. It was formerly a place of more importance than at present; but the harbour has been neglected, and nearly choked up by sand. It is sometimes called Meeching. The population amounted in 1801 to 584, in 1811 to 755, in 1821 to 927, and in 1831 to 904.
