An ejector and a refrigeration cycle apparatus having an ejector are provided. The ejector may include an ejector body having an accommodation space therein, a suction portion through which a high pressure refrigerant and a low pressure refrigerant may be suctioned into the accommodation space, and a mixing portion configured to mix the high pressure refrigerant with the low pressure refrigerant; a nozzle provided in the ejector body, having a nozzle neck and an expansion portion, and configured to inject the high pressure refrigerant into the mixing portion; a first needle moveably provided at the expansion portion, and configured to control a flow sectional area of the expansion portion; a second needle moveably provided at the nozzle neck, and configured to control a flow sectional area of the nozzle neck; a first needle drive configured to drive the first needle; and a second needle drive configured to drive the second needle. With such a configuration, the flow sectional area of the nozzle neck and the flow sectional area of the expansion portion may be independently controlled in correspondence to a drive condition.
