The invention relates to a gray glass composition and vehicle window glass. The gray glass composition comprises a basic component and a coloring component, wherein the coloring component comprises the following components in percentage by mass in the gray glass composition: 0.5%-1.5% of total iron (Fe2O3), 10 ppm to 50 ppm of selenium (Se), 100 ppm to 500 ppm of chromium oxide (Cr2O3), 50 ppm to 300 ppm of cobalt oxide (CoO), 10 ppm to 150 ppm of manganese oxide (MnO2) and 10 ppm to 100 ppm of tin oxide (SnO2). The gray glass composition has the comprehensive performance of low visible light transmittance, low infrared ray transmittance, low ultraviolet ray transmittance and low solar energy direct transmittance, has a neutral gray hue meeting visual comfort, and also has great economic advantages.
