Abstract: Provided are an iron oxide dispersion for ink jet recording, a method of manufacturing the same, and an ink jet recording method. The iron oxide dispersion for ink jet recording includes: iron oxide particles; a resin that has at least one of an amino group or a quaternary ammonium group and coats at least a part of surfaces of the iron oxide particles; and water, in which an average particle diameter of the iron oxide particles having surfaces at least a part of which are coated with the resin is 90 nm to 400 nm.
