Eradi is a Samanthan clan of Kshatriya origin, coming from the Indian state of Kerala. The word is derived from the place name Eranad in Kerala. The "Samoothiri" (Zamorin) comes from this Eradi subcaste, now assimilated to Samantha Kshatriya, the major upper caste of state of Kerala. Historically the Eradis numbered only a few hundreds of members. The 1891 Census of India reported their population at just 356, constituting less than 0.04% of the total Nair population.
