The origin of the name "Ramamangalam" is believed to come from Lord Rama, a widely revered Hindu deity. According to the belief, shortly after their marriage, Lord Rama and Sita Devi visited the village during their vanavasa from Ayodhya on the demand of his stepmother, Kaikeyi. The village was subsequently named as Sriramamangalam, later shortened to Ramamangalam.[2]
