独立悬吊系统(Independent suspension)是一种车辆的悬吊系统，即是将左右的车轮起伏分开，能在崎岖道路上行驶的设备。

汽车底盘独立悬挂系统可使左右两边车轮独立跳动起伏，不会互相拉扯影响车辆行驶平衡，增加操控性与舒适性，只是成本较非独立悬吊（如固定轴悬吊）高。

Independent suspension is a broad term for any automobile suspension system that allows each wheel on the same axle to move vertically (i.e. reacting to a bump in the road) independently of each other. This is contrasted with a beam axle or deDion axle system in which the wheels are linked – movement on one side affects the wheel on the other side. Note that "independent" refers to the motion or path of movement of the wheels/suspension. It is common for the left and right sides of the suspension to be connected with anti-roll bars or other such mechanisms. The anti-roll bar ties the left and right suspension spring rates together but does not tie their motion together.
