Head-up display glass and a head-up display system are provided in the present disclosure. The head-up display glass includes outer glass, inner glass, an interlayer, and a reflective coating. The interlayer is disposed between a second surface of the outer glass and a third surface of the inner glass. The reflective coating is disposed on a fourth surface of the inner glass. The reflective coating can reflect P-polarized light. The reflective coating includes at least one low-emissivity layer and at least one laminated structure that are stacked in sequence. Each laminated structure includes a high-refractive-index layer and a low-refractive-index layer that are stacked in sequence. In each laminated structure, the high-refractive-index layer is closer to the fourth surface than the low-refractive-index layer. A refractive index of the high-refractive-index layer is greater than or equal to 1.8. A refractive index of the low-refractive-index layer is less than 1.8. The present disclosure can take account of multiple performance of head-up display (HUD), heat insulation, and low radiation, so that a driver or a passenger can more sharply observe a sharp head-up display image without ghosting.
