Kraljevina Nri je naziv za nekadašnju državu, odnosno sistem društvene organizacije Nri-Igboa, jedne od podgrupa naroda Igbo u današnjoj Nigeriji. Njeno osnivanje se tradicionalno pripisuje legendarnom kralju Eriju koji se oko 948. spustio
s neba i osnovao plemena Igboa. Njegovu vlast su kasnije preuzeli namjesnici/zamjenici koji su nosili titulu eze Nri. Za njih je bilo karakteristično da iza sebe nisu imali vojsku niti oružanu silu, nego su djelovali više kao svećenici, odnosno kao posrednici u sporovima. Vrhunac uticaja je Nri Kraljevstvo imalo od 13. do 17. vijeka, kada se na njegovom području počeli uticati sukobi sa susjednim državama kao i transatlantska trgovina robljem. Nakon što su na području Nigerije vlast preuzeli Britanci, godine 1911. su posljednjim ezeima oduzeli sve svjetovne ovlasti, čime je Kraljevstvo formalno prestalo postojati. Posljednjih decenija među Igboima traju pokušaji da se Kraljevstvo Nri obnovi kao duhovna i kulturna institucija.
