A cobalt carbide-based catalyst for direct production of olefin from synthesis gas, a preparation method therefor and application thereof are disclosed. The method for preparing the catalyst comprises the following steps: 1) mixing a cobalt source with water, or mixing a cobalt source, an electron promoter and water to obtain a first solution; and mixing a precipitant with water to obtain a second solution; 2) adding the first solution and the second solution to water, or water and a structure promoter for precipitation, crystallizing, separating, drying and calcination; and 3) reducing a solid obtained in Step 2) in a reducing atmosphere, and then carbonizing in a carbonizing atmosphere. The prepared catalyst has high activity and high selectivity to olefins for direct production of olefins via syngas conversion.
