Obasinjom (Ejagham 'Obasi' God + 'njom' cult-agency/medicine, 'God's medicine'; Basinjom among neighbouring Cross River peoples) is a divinatory medicine-spirit of the Ejagham, regarded as superior to other cult agencies. It is made present in a crocodile-headed masked figure, omniscient and clairvoyant, that comes out to detect and expose witches and other hidden wrongdoers, serving the community at once as detective, judge and healer. Documented by Talbot in the early twentieth century and the subject of detailed modern study by Ute Röschenthaler, Obasinjom spread by purchase from village to village across the Cross River region of Nigeria and Cameroon, well beyond its Ejagham origins.
