Pedro de Portocarrero was a Spanish conquistador who was active in the early 16th century in Guatemala, and Chiapas in southern Mexico. He was one of the few Spanish noblemen that took part in the early stages of the Spanish conquest of the Americas, and was distantly related to prominent conquistador Pedro de Alvarado, who appointed him as an official in early colonial Guatemala.

Pedro de Alvarado 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 the Aztec Empire led by Hernán Cortés. He is considered the conquistador of much of Central America, including Guatemala, Honduras, and El Salvador.
