a market-town of England, in the West Riding of Yorkshire, on a flat spot on the right bank of the Ouse, 14 miles S. by E. of York, and 175 N.N.W. of London. It is well though irregularly built, consisting of four principal streets, meeting in a central market-place, in which stands an old Gothic cross. The most conspicuous edifice is the noble old parish church, which originally formed part of a Benedictine abbey, founded by William the Conqueror in 1068. It is cruciform in plan, partly in the Norman and partly in the early English styles; its dimensions are 267 feet by 100. In it are some fine specimens of stained glass and carved stone-work. The other places of worship in the town belong to Wesleyan and Primitive Methodists, Independents, Baptists, Quakers, Roman Catholics, and Unitarians. Among the public buildings of Selby there are also a town-hall, and another hall for public meetings, erected in 1841. There are various schools and libraries, a mechanics' institution, and a news-room. The manufacturing establishments include boat-building yards, iron and brass foundries, breweries, tanneries, sailcloth and rope manufactories. The river is navigable up to Selby for vessels of 200 tons, and is crossed here by a moveable wooden bridge. A considerable trade is carried on in corn and cattle, as well as in the produce of the manufactures. Besides weekly markets, several annual fairs are held here. Pop. (1851) of the town, 5109; of the parish, 5340.
