Provided is a fiber reactive dye composition which can dye or print cellulose based fiber materials or materials containing the fiber materials uniformly with good build-up property and reproducibility and give dyed or printed products excellent in various fastness properties. A fiber reactive dye composition which comprises at least five reactive dyes selected from the groups of reactive dyes represented by the following formulas (I) to (VII) respectively in the form of free acid: wherein R1 and R2 are each hydrogen, alkyl, ureido or the like, R5 and R6 are each hydrogen, sulfo or the like, R3, R4, R7 to R13 and R15 to R18 are each hydrogen, alkyl or the like, R14 is -O- or A, B, D, E, G, J and L are each phenylene or the like, X1 to X6 are each halogen, Y1 to Y7 are each -SO2CH=CH2 or -SO2C2H4Z, Z being a group capable of being split off by the action of an alkali, m1 to m4 are each an integer of 1-3, and n is 0 or 1, provided that the composition contains respectively at least one yellow dye selected from those of the formulas (I) and (II), red dye selected from those of the formulas (III) and (IV) and blue dye selected from those of the formulas (V) to (VII).
