机上娱乐又可称作飞行娱乐，是指航空公司给乘客在客机上使用的娱乐方式，使旅客可打发在机上的时间。1936年，兴登堡号飞艇曾给往返于欧洲和美国的乘客提供钢琴、休息室、饭厅、吸烟室和酒吧等设备。第二次世界大战后，飞行娱乐逐渐转换为饮食和放映影片等服务。1985年，出现了个人多媒体播放器和耳机。1990年代开始，娱乐设备成为航班不可或缺的一部分，也是机舱设计的一个重要因素。飞机内娱乐设备的设计需要考虑安全性、成本、软件和硬件的可靠性、用户使用体验等诸多方面。随着科技发展，飞行娱乐的方式也在不断改变。

In-flight entertainment (IFE) refers to the entertainment available to aircraft passengers during a flight. In 1936, the airship Hindenburg offered passengers a piano, lounge, dining room, smoking room, and bar during the 2 1/2 day flight between Europe and America. After the Second World War, IFE was delivered in the form of food and drink services, along with an occasional projector movie during lengthy flights. In 1985 the first personal audio player was offered to passengers, along with noise cancelling headphones in ****. During the 1990s the demand for better IFE was a major factor in the design of aircraft cabins. Before then, the most a passenger could expect was a movie projected on a screen at the front of a cabin, which could be heard via a headphone socket at his or her seat. Now, in most aircraft, private IFE TV screens are offered on most airlines.
