Ekapāda (Ekapada) was an ancient non-Aryan tribe. During his digvijaya, expedition, Sahadeva conquered the Ekapāda tribe, living in the southern countries. They paid allegiance to the Pāṇḍava (Pandava), by paying revenue to them.
The presence of the Ekapāda tribe was found in Indraprasrha suting the Rājasūya yajña (Rajasuya yajna) of Yudhiṣṭhira (Yushishthita). In Sabhāparva (Sabhaparva), the description of these people is given as follows — they have two or three eyes; they wear turbans upon their heads, but no clothing over their bodies. Their bodies are covered with hairs. They are carnivorous and they move with one leg–
dvyakṣāṁstrakṣān lalāṭākṣān nānādigbhyaḥ samāgatān.
auṣṇīṣānastavāmāṁśca romakān puruṣāsakān.
ekpādāṁśca tatrāhamapaśyaṁ dvāri vāritān.
From the description of the Ekapāda people waiting outside the yajña-place of Yushiṣṭhita, it appears that they belonged to a marginalised, non-Aryan community.
