偏振片（英语：Polarizer）是一种光学物理学中的术语，指可以使天然光变成偏振光的光学组件叫偏振片（或称偏光板、偏光膜）。根据获取方式分类，可分为天然偏振片、人造偏振片。天然偏振片可以由具有特殊分子排列的晶体制成，通常很难找到合适的晶体，加工比较考究，很难获得，因此价格昂贵。人造偏振片由于制造工艺简单、价格便宜，并可制成较大面积，因而得到广泛的应用。

Full polarization at Brewster's angle requires many more plates than shown. The arrows indicate the direction of the electrical field, not the magnetic field, which is perpendicular to the electric field$ A polarizer or polariser is an optical filter that passes light of a specific polarization and blocks waves of other polarizations. It can convert a beam of light of undefined or mixed polarization into a beam with well-defined polarization, polarized light. The common types of polarizers are linear polarizers and circular polarizers. Polarizers are used in many optical techniques and instruments, and polarizing filters find applications in photography and liquid crystal display technology. Polarizers can also be made for other types of electromagnetic waves besides light, such as radio waves, microwaves, and X-rays.
