Provided are: an extractant which is capable of quickly and highly efficiently extracting zirconium from an acidic solution that is obtained by acid leaching a material containing zirconium and scandium such as an SOFC electrode material; and a method for extracting zirconium, which uses this extractant. A zirconium extractant according to the present invention is composed of an amide derivative represented by general formula (I). In the formula, R1 and R2 respectively represent the same or different alkyl groups, each of which may be linear or branched; R3 represents a hydrogen atom or an alkyl group; and R4 represents a hydrogen atom or an arbitrary group other than an amino group, said arbitrary group being bonded, as an amino acid, to the α carbon.
