电影摄影机是一种摄影相机。相对于静态相机只捕捉瞬间的单一快照，电影摄影机可透过间歇性机构连续快速拍摄「系列影像」（帧／影格／画面）于底片条上，随后再透过电影放映机以特定速度（帧率）播放，因为视觉暂留效应而组成动态影像。

自19世纪晚期发明以来，电影摄影机一度非常流行用于私人摄影，直到被它的后继者摄录像机所取代。如今，许多电影摄影机摇身一变成为收藏品，也有爱好者组成规模不大但组织完善的小社团，持续经营电影摄影机这项嗜好，即使多数相关零件和设备早已停产。

The movie camera, film camera or cine-camera is a type of photographic camera which takes a rapid sequence of photographs on an image sensor or on a film. In contrast to a still camera, which captures a single snapshot at a time, the movie camera takes a series of images; each image constitutes a "frame". This is accomplished through an intermittent mechanism. The frames are later played back in a movie projector at a specific speed, called the frame rate (number of frames per second). While viewing at a particular frame rate, a person's eyes and brain merge the separate pictures together to create the illusion of motion.
