SAN PAULO, a province of Brazil, lying between S. Lat. 20. and 24. 30., W. Long. 44. 30. and 53.; bounded on the N. by the provinces of Goyaz and Minas Geraes, N.E. by that of Rio de Janeiro, S.E. by the Atlantic, S. by Curitiba, and W. by Parana. Area, 170,615 square miles. The coast line is about 400 miles in length, and stretches from N.W. to S.E.; along the shore is a narrow strip of low land, and beyond it rises a ridge of mountains extending in a parallel direction. These form the watershed of the province, dividing it into two very unequal portions; the rivers of the eastern part flowing directly into the Atlantic, and those on the other side reaching the same destination through the Parana, which forms part of the northern and the whole of the western boundary of the province. The mountains are for the most part of granite formation, and their upper parts are covered with dense forests of valuable timber, especially cedar and pine. Their lower slopes, and the country as far as the Parana, are almost all exceedingly fertile. The principal affluent of the Parana in this province is the Tiete, which flows from east to west very nearly in the centre of the country. Grain, rice, and manise, are the principal crops raised in the interior. Along the coast, tobacco, sugar, and cotton are cultivated. Horses and cattle are reared in great numbers on the tablelands in the central parts of the province. The extreme portion is still occupied by aboriginal tribes. There are several seaports along the coast, by means of which a considerable trade is carried on with Rio Janeiro. San Paulo is divided into 7 comarcas; and represented in the legislature of Brazil by four senators and nine deputies. Pop. (1856) 500,000.
