A silver halide color photographic light-sensitive material comprises a novel cyan dye-forming coupler or a combination of a specific cyan dye-forming coupler with an .alpha.-pivaloylacetoanilide type yellow dye-forming coupler or a pyrazoloazole type magenta dye-forming coupler, the specific cyan dye-forming coupler being contained in the silver halide emulsion layer in the form of an emulsion of lipophilic fine particles obtained by mixing the coupler with at least one water-insoluble and organic solvent-soluble homo- or co-polymer to form a dispersion. The silver halide color photographic light-sensitive material is excellent in the reproduction of yellow, magenta and cyan colors and has low fog of cyan. Thus, the light-sensitive material can provide color images excellent in the fastness of the cyan color images.The cyan dye-forming coupler is represented by general formula (II): ##STR1## wherein R.sub.1 represents an aliphatic group, an aromatic group or a heterocyclic group; R.sub.2 represents a group or atom which can be bonded with the heterocyclic ring; X represents a hydrogen atom or a group which can be eliminated; Y represents a divalent bonding group having at least one amido bond and/or ester bond; Z represents a dissociative group; A, B, C, D and E each represents a nitrogen atom or a carbon atom a which hydrogen atom is bonded, provided that one or two of them represent a nitrogen atom; and n represents 0, 1 or 2.
