雷射影碟（英文：LaserDisc，缩写：LD），是种于1980至90年代中流行的影像保存媒体，主要用作保存电影，后被数码多功能影音光盘完全代替。

雷射影碟尺码和12吋黑胶唱片相若，表面和音乐光盘相似。雷射影碟机以雷射读取预先刻录在盘片上的信号，并且转换成为影像信号（如PAL制式及NTSC制式）供电视机播放。于1980年代相对当时流行的家用录像系统录像带是颇昂贵的东西。雷射影碟能够提供的影像质素接近广播电视，而且因为是非接触式读取的关系，没有录像带使用多次会造成影像变差的问题。

很多人以为雷射影碟使用了数字技术，但其实不论影像和声音都是使用频率调制的模拟方式保存在影碟上。后期的NTSC影碟才真的可以将音轨以数码方式（主要是脉冲编码调制或Dolby Pro Logic）加载到碟上，PAL影碟则只能以数字或模拟其中一种方法保存音轨。

LaserDisc (LD) is a home video format and the first commercial optical disc storage medium, initially licensed, sold, and marketed as MCA DiscoVision (also known as simply "DiscoVision") in North America in 1978.

Although the format was capable of offering higher-quality video and audio than its consumer rivals, the VHS and Betamax videocassette systems, LaserDisc never managed to gain widespread use in North America, largely due to high costs for the players and video titles themselves and the inability to record TV programming. It also remained a largely obscure format in Europe and Australia. By contrast, the format was much more popular in Japan and in the more affluent regions of Southeast Asia, such as Hong Kong, Singapore, and Malaysia, being the prevalent rental video medium in Hong Kong during the 1990s. Its superior video and audio quality did make it a somewhat popular choice among videophiles and film enthusiasts during its lifespan.
