Leasburg Dam State Park is a state park of New Mexico, United States, located on the Rio Grande north of Las Cruces.. It provides opportunities for camping, hiking, picnicking, swimming, and wildlife viewing. Nearby is the historic Fort Selden State Monument.
The dam at Leasburg was completed in 1908 to divert water into canals for nearby farms in the Mesilla Valley. Early settlers used the area as a passage to El Camino Real and the Jornada del Muerto.
