诱导阻力（英语：induced drag）在空气动力学中，诱导阻力是一个相对着空气流动的物体中，和该物体运动方向相反的力。诱导阻力有着跟攻角成正比增加的特性，作用在任何因外形能改变空气流向以产生升力的物体。例如飞机机翼产生向上的升力和汽车扰流板产生向下的下洗力。升力有增减，诱导阻力也跟着增减；当升力降至零，诱导阻力也随之消失。

In aerodynamics, lift-induced drag, induced drag, vortex drag, or sometimes drag due to lift, is an aerodynamic drag force that occurs whenever a moving object redirects the airflow coming at it. This drag force occurs in airplanes due to wings or a lifting body redirecting air to cause lift and also in cars with airfoil wings that redirect air to cause a downforce. With other parameters remaining the same, induced drag increases as the angle of attack increases.
