Bresse (Arpitan: Brêsse) is a former French province. It is located in the regions of Rhône-Alpes, Bourgogne, and Franche-Comté of eastern France. The geographical term Bresse has two meanings: Bresse bourguignonne (or louhannaise), which is situated in the east of the department of Saône-et-Loire, and Bresse, which is located in the department of Ain. The corresponding adjective is bressan, and the inhabitants are Bressans.

Bresse extends from the Dombes River on the south to the Doubs River on the north, and from the Saône eastwards to the Jura mountains, measuring some 60 miles in the former, and 20 miles in the latter direction. It is a plain varying from 600 to 800 feet above the sea, with few eminences and a slight inclination westwards. Heaths and coppice alternate with pastures and arable land; pools and marshes are numerous, especially in the north. Its chief rivers are the Veyle, the Reyssouze and the Seille, all tributaries of the Saône. The soil is a gravelly clay but moderately fertile, and cattle-raising is largely carried on. The region is, however, more especially celebrated for its table poultry.
