The invention provides a method for preparing cis-1-amino-2-fluorocyclopropane. A preparation process comprises 8 to 10 steps. A structural formula of the cis-1-amino-2-fluorocyclopropane is represented by a formula 1 shown in the description, and the form of benzene sulfonate or hydrochloride is relatively common. An important intermediate product, i.e., cis-fluoro-amine olefin 2 is synthesized. The method has the advantages that the consumption of diiodo-fluoromethane or dibromo-fluoromethane, which is expensive in price and causes heavy pollution in a raw material production process, is avoided; a cis triatomic ring is obtained through the cyclization of high-activity cis-olefin 2, and an absolute-configuration product can be obtained by only one-time resolution, so that the method has especially great advantages in the aspect of either economical efficiency of the raw materials, or the difficulty of resolution of isomers.
