A process for removing a metal from a crude oil includes contacting the crude oil containing the metal with a crude-immiscible ionic liquid to produce a crude oil and crude-immiscible ionic liquid mixture, and separating the mixture to produce a crude oil effluent having a reduced metal content relative to the crude oil feed. Optionally, a de-emulsifier is added to at least one of the contacting and separating steps.
