The gallium extraction agent comprises an amide derivative represented by general formula (I). In the formula, R1 and R2 each indicate the same or different alkyl group, R3 indicates a hydrogen atom or an alkyl group, and R4 indicates a hydrogen atom or any given group, other than an amino group, bonded to the α-carbon as an amino acid. The general formula preferably has a glycine unit, a histidine unit, a lysine unit, an aspartic acid unit, or an N-methylglycine unit. By extracting gallium from an acidic solution containing gallium and zinc by means of solvent extraction using the extraction agent, it is possible to selectively extract gallium.
