幽浮学（Ufology）或飞碟学或UFO研究是指研究不明飞行物体（UFO）报告、目击事件、物理现象与相关奇异现象的一门学问。

虽然有许多幽浮学家努力争取科学界的认同，但是即使有一些具有名望的学者（例如约瑟夫·艾伦·海尼克、詹姆斯·麦当劳、雅克‧瓦莱（Jacques Vallee）、彼得·斯迪罗克（Peter Sturrock）等人）参与研究，飞碟学仍然不受到主流科学界的注意。

Ufology (pronounced yoo • faw • la • jee) is loosely defined as the study of reports, visual records, physical evidence, and other phenomena related to unidentified flying objects (UFO). UFOs have been subject to various investigations over the years by governments, independent groups and scientists, but ufology as a field of study has yet to be embraced by academia.
