Castillo de Arribalavilla, also known as Castillo de Zalamea de la Serena, is a 15th-century fortress of Islamic origin rebuilt during Christian times in Zalamea de la Serena, Badajoz province, Extremadura, Spain.

Captured in 1232 by King Fernando III with the Order of Alcántara, it features a rectangular layout with four distinctive corner towers - del Homenaje, Mocha, Oscura, and de la Higuera along with almenas, aspilleras, and a Gothic palace facade added by Maestre Juan de Zúñiga, who hosted scholars like Antonio de Nebrija there.

Archaeological layers reveal Roman, medieval, and even pre-Roman remains around its central aljibe and patio, with the site later housing a 19th-century cemetery before preservation as a historic ruin.
