静电单位制（英语：electrostatic unit）是衍生自厘米-克-秒制（CGS制）的一套单位系统，用来量测电荷、电流及电压等电学的物理量。在静电单位制中，电荷以其对其他电荷所施的力来定义。虽然CGS制已经被国际单位制所取代，但在一些特定的物理学领域中仍会用到静电单位制，例如粒子物理学及天体物理学。

在静电单位制下，库仑定律可用以下的形式表示

静电单位制的主要单位有：

The electrostatic system of units is a system of units used to measure electrical quantities of electric charge, electric current, and voltage within the centimeter-gram-second (or "CGS") system of metric units. In electrostatic units, electrical charge is defined by the force that it exerts on other charges. Although the CGS units have mostly been supplanted by the MKSA (meter-kilogram-second-ampere) or International System of Units (SI) units, the electrostatic units are still in occasional use in some applications, most notably in certain fields of physics such as in particle physics and astrophysics.
