A multiple cyclone dust collector is provided to increase capacity of a primary dust storage unit by modifying the shape of a secondary cyclone. A multiple cyclone dust collector comprises: a case(10) forming the appearance; a primary cyclone dust collecting unit(100) installed in the case; and a secondary cyclone dust collecting unit(300) connected with the primary cyclone dust collecting unit. The primary cyclone dust collecting unit has a first inflow unit(120), a first body(140), a first dust storage unit(170), and a first outflow unit(190). The secondary cyclone dust collecting unit is installed at the outer side of the primary cyclone dust collecting unit so as to separate foreign matters from air flowed through the first outflow unit, and formed with a second inflow unit(320), a second body(340), and a second outflow unit(390).
