La Joyanca is the modern name for a pre-Columbian Maya archaeological site located south of the San Pedro Martir river in the Petén department of Guatemala. It is east of the Maya site of La Florida (Namaan), now the modern town of El Naranjo on the Mexico-Guatemala border. The site was discovered in 1994 during the construction of the Xan-La Libertad oil pipeline in Guatemala. It was immediately recognized as an important, undiscovered Classic period (AD 200-900) Maya city and became the focus of an archaeological project. Directed by Charlotte Arnauld, Erik Ponciano, and Veronique Breuil, the La Joyanca project conducted excavations here between 1998 and 2003. Several members of this group have continued work at other related locations in the Northwest Peten, including the sites of Zapot
