Antioquia, one of the nine states of the United States of Colombia, between lat. 5° 3' and 8° 9' N., and Ion. 74° 3' and 76° 13' W., touching the gulf of Darien on the N. TV., and bounded by the states of Bolivar, Santander, Cundinamarca, Tolima, and Cauca; area, 24,823 sq. m.; pop. in 1870, 365,974, about 20 per cent. white, the remainder mestizos (mixed white and Indian), mulattoes, and Indians, chiefly civilized. The central range of the Andes spreads out over nearly the whole state, terminating in its E. and N. E. portions. The river Cauca flows through its entire length, and the Magda-lena forms the E. boundary, and is navigable for steamers of light draught. Antioquia is rich in gold, and although the mines and washings are but little worked, the annual produce is estimated at $2,500,000. The soil is extremely fertile, and the valleys lying between the various mountain ranges abound in cattle. Springs impregnated with iodine abound throughout the state, to which is attributed the exemption of the inhabitants from goitre, which prevails in other parts of the republic.

The principal cities are Medellin, the capital, Ca-ceres, Remedies, and Zaragoza.
