A wire rope vibration isolator is adapted to separate vibrations, mitigate impacts and reduce structural noises and includes a first fixed seat, a second fixed seat and a plurality of wire ropes. The wire ropes are separated from each other and respectively disposed between the first fixed seat and the second fixed seat. Moreover, the wire rope vibration isolator has a good damping effect in three-D directions to increase reliability and stability for precision machinery or products in working or moving processes, and the wire rope vibration isolator can reduce high-frequency noises. Hence, the wire rope vibration is safe and reliable, when it bears great impacts. Furthermore, the wire rope vibration isolator is easily assembled and used.
