Iğdır Province is situated in the Eastern Anatolian Region of Turkey. Wild edible plants and their utilization methods have not been previously documented there. This study was conducted during an ethnobotanical survey of Iğdır Province from 2007 to 2012, in the period from May to October, when plants were in their flowering and fruiting periods. There were 210 interviews carried out in 78 villages. This study provides information about 154 wild plant taxa belonging to 27 families that have been used as foodstuffs, spices, or hot drinks. Seventeen wild edible plants were recorded for the first time during this study. Eight endemic species were reported as used for their edibility, and new local names for plants were also recorded. The cultural importance index was calculated for each taxon. The most culturally important species are <em>Mentha longifolia</em>, <em>Falcaria vulgaris</em>, <em>Polygonum aviculare</em>, <em>Rosa canina</em>, <em>Crataegus azarolus</em>, <em>Capsella bursa-pastoris</em>, and <em>Malus sylvestris</em>. This study presents the richest heritage in terms of the diversity of wild edible plants ever recorded in Turkey.
