The Haina River is a river of the Dominican Republic.
In 1496, according to Floyd, "Miguel Diaz and Francisco de Garay, working their way down the Haina river, discovered rich deposits of gold in the river sands perhaps twenty-five miles from the coast." Bartolome Colon built a fort along this river, "well situated within the gold region", which he named San Cristobal.
