The purpose of the present invention is to provide an anionic surfactant composition for emulsion polymerization use, which can exert excellent polymerization stability even when used in a smaller addition amount, enables the production of a polymer emulsion having smaller particle diameters, and also enables the production of a polymer emulsion having excellent mechanical stability and chemical stability. An anionic surfactant composition for emulsion polymerization use, which comprises a component A that is an anionic surfactant represented by formula I and a component B that is at least onecomponent selected from anionic surfactants represented by formulae II to IV. In formula I, R1 represents a C6-26 hydrocarbon group; M+ represents a hydrogen ion or a cation; and m (an average numberof moles added) represents 10 to 100. In formulae II to IV, R2 and R3 independently represent a C8-26 hydrocarbon group; R4 represents a C6-18 hydrocarbon group; Q+ represents a hydrogen ion or a cation; and n (an average num
