Deir Samaan (Arabic: دير سمعان, lit. 'Monastery of Samaan') is one of the largest Byzantine agricultural farms in Samaria and is located in Leshem, West Bank, Palestine. The site which has been impressively preserved dates back to the Roman period. The farm, which was established on the side of the main road at the time, includes many agricultural facilities, including houses, sheds, water cisterns, storage ponds and more. Despite the site's name, no monks are known to have been active there, and it seems that the name was intended to emphasize the farm's Christian ownership.
