Provided are a method for manufacturing a polarizer, a polarizer manufactured by the same, and a polarizing plate including the same. The method for manufacturing a polarizer comprises the steps of stacking a polyvinylalcohol-based film on at least one surface of a polymer film to form a stacked body; dry-stretching the stacked body; and coating an aqueous solution including a dichroic dye aqueous solution on the polyvinylalcohol-based film of the stretched stacked body.
