预知（precognition），是一种超感官知觉，让「感知者」能「感知」到（而不是由已有的知识推理出）未来会发生的事。又称特异功能。

有个相关的词叫「预感」，是指一种人心中关于未来事件的信息。这种信息比较接近感觉而非知识。有些人认为这些都算是透视的特例。

在佛经（Buddhism Sutra）中，经常有记载佛的“授记”，授记就是一种预言。而预言，似乎比预感更为主动一些，是神佛（或人们）对未来将会发生的事情，作定时、定量、定性的「缺省定」。而在圣经和佛经中，神化肉身为人子耶稣的“特异功能”所引发的“奇迹”和佛的“特异功能”也大量的被记载。这些都可以为现代超心理学、现代心灵学和超能力现象研究的学者们参考。

Precognition (from the Latin præ-, "before" and cognitio, "acquiring knowledge"), also called future sight, and second sight, is an alleged psychic ability to see events in the future.

As with other forms of extrasensory pe****tion, there is no evidence that precognition is a real ability possessed by anyone. However, it still appears within movies, books, and discussion within the parapsychology community, with claimed precognition of earthquakes sometimes covered by the newsmedia.
