Ethyl diazoacetate (N=N=CHC(O)OC₂H₅) is a diazo compound and a reagent in organic chemistry. It was discovered by Theodor Curtius in 1883.^[3] The compound can be prepared by reaction of the ethyl ester of glycine with sodium nitrite and sodium acetate in water.

It is used in the cyclopropanation of alkenes.

Although the compound is hazardous it is used in chemical industry.^[4] Procedures for safe industrial handling have been published ^[5]
