Field study was carried out in 24 villages of Koraput district of Odisha and the ethnomedicinal information was collected through interview among different tribal group and traditional healers. The use value, informant consensus factors (FIC) and fidelity level (FL) were analyzed to know the important ethnomedicinal tubers used by the tribals. A total of 56 species of tubers distributed in 35 genera belonging to 21 families were identified as commonly used tubers by the tribals and traditional healers for the treatment of 37 types of diseases. These diseases were categorized into 11 ailment categories based on the body systems treated. Most of the medicines were prepared in the form of paste and administered orally. FIC values of the present study indicated that there was a high agreement among the users for the use of plants in the treatment of toothache, cough, nose bleeding and to increase milking of pregnant mother. Six species had highest fidelity level of 100%. The most important species according to their use value were Dioscorea oppositifolia, Colocasia esculenta, Cheilocostus speciosus, Dioscorea pentaphylla, Manihot esculenta, Curcuma longa, Curcuma angustifolia, Dioscorea alata, Dioscorea belophylla and Dioscorea tomentosa.
