a town of France, in the department of Somme, on the slope of a hill in the midst of marshes, on the right bank of the Somme, 30 miles E. of Amiens. It is strongly fortified, and has a ruined castle, in one of whose towers Charles the Simple died in captivity, and Louis IX. was imprisoned by Charles the Bold of Burgundy. There are two suburbs; and the houses are well built. The chief buildings are the church of St John (a fine Gothic edifice), an ancient belfry, a town-hall, convent, hospital, theatre, and college. Manufactures of woollen and cotton stuffs, lawn, cambric, leather, sugar, and other articles are carried on here; and there is some trade in grain, wool, and brandy. Péronne was a place of much importance in the middle ages, and bore the name of La Pucelle ("The Maiden City"), as it was never captured till Wellington took it eight days after the battle of Waterloo. Pop. (1856) 4102.
