Swaroopathil Nairs or Charna Nairs are Hindu Malayala Kshatriya caste in the southern Indian state of Kerala, one of the subcastes belonging to the Nair community in Kerala. They were warriors of Samanta Kshatriya Royal Households known as Swaroopams. This subcaste is found only in Travancore. In Malabar, two related subcastes, Akathu Charna Nairs and Purathu Charna Nairs are treated as equivalent to Swaroopathil Nairs in caste hierarchy.
According to the 1891 Census, Swaroopathil Nairs composed around 9.2% of the total Nair population, while Akathu Cherna and Purathu Cherna Nairs accounted for 3.3% and 11.1% respectively.[page needed]
