A method for preparing an aramid nanofiber dispersion includes dissolving an aromatic polyamide-based polymer in a solution including a basic material and an aprotic polar solvent, while performing stirring so that a nanofiber is produced, wherein the aromatic polyamide-based polymer is a polymer in a form of a solid which is not spun into a fiber form, the stirring is performed at a temperature of 50° C. or lower and at a speed of 10-1000 rpm so that a time taken for the aromatic polyamide-based polymer to be dissolved and formed into an aramid nano-fiber dispersion is 80 hours or less, an aramid nanofiber in the aramid nanofiber dispersion has an average diameter of 1 to 100 nm and an average length of 0.1 to 100 μm, and the basic material includes potassium hydroxide or sodium hydroxide.
