Russian Fort Elizabeth is a National Historic Landmark and is administered as the Russian Fort Elizabeth State Historical Park just southwest of present day Waimea on the island of Kauai in Hawaii. It is located at the site of the former Fort Elizabety (), the last remaining Russian fort on the Hawaiian islands, built in the early 19th century by the Russian-American Company as the result of an alliance with High Chief Kaumualii. It was employed by the Kingdom of Hawaii in the 19th century under the name Fort Hipo ().
