The refractive index dispersion data of the single crystal yttrium iron garnet are obtained from reflectivity measurements on natural crystal faces. The esults are analyzed using Sellmeier three-term oscillator and power series expression. The deviation of measured and calculated refractive index is about 0.003 over the wavelenth range 0.5 to 5.5 μm
