佩德罗·德·阿尔瓦拉多（西班牙语：Pedro de Alvarado，约1485年－1541年7月4日）是一位西班牙征服者、危地马拉总督。他参加了征服古巴的行动，并征服了危地马拉、墨西哥、秘鲁一带。

Pedro de Alvarado y Contreras (Badajoz, Extremadura, Spain, ca. 1485 – Guadalajara, New Spain, 4 July 1541) was a Spanish conquistador and governor of Guatemala. He participated in the conquest of Cuba, in Juan de Grijalva's exploration of the coasts of the Yucatán Peninsula and the Gulf of Mexico, and in the conquest of Mexico led by Hernán Cortés. He is considered the conquistador of much of Central America, including Guatemala, Honduras and El Salvador. Although renowned for his skill as a soldier, Alvarado is known also for the cruelty of his treatment of native populations, and mass murders committed in the subjugation of the native peoples of Mexico.
