A silver halide photographic emulsion containing, in supersensitizing amounts, a combination of at least one benzimidazolocarbocyanine dye wherein an aralkyl group substituted with an acidic group is connected to at least one nitrogen atom in the imidazole ring, which is represented by the following general formula (I): <IMAGE> (I) wherein V1, V2, V3 and V4, which may be the same or different, each represents a hydrogen atom, a halogen atom, an alkyl group, an alkenyl group, a cycloalkyl group, an acyl group, an acyloxy group, an alkoxycarbonyl group, a carbamoyl group, a sulfamoyl group, a cyano group, a trifluoromethyl group or a hydroxy group; R1, R2 and R3, which may be the same or different, each represents an aliphatic group; A represents a sulfo group of a carboxy group; X1 represents an acid residue; h represents an integer from 1 to 6; and i represents 0 or 1; and at least one cyanine dye represented by the following general formula (II): <IMAGE> (II) wherein Z1 represents the atoms necessary to complete a thiazole ring or a selenazole ring; Z2 represents the atoms necessary to complete a thiazole ring, a selenazole ring or an oxazole ring; R4 represents a hydrogen atom, an aliphatic group or an aryl group; R5 and R6, which may be the same or different, each represents an aliphatic group; X2 represents an acid residue; and l and n each represents 0 or 1; which demonstrates reduced fog, reduced residual color and high sensitivity, and, further, which is endowed with desirable spectral sensitization distribution and minimized deterioration with the lapse of time under high temperature and humidity conditions.
