裘安纳·斯哥德·艾儒吉纳（英语：Johannes Scotus Eriugena， c. 815 – c. 877），又称爱留根纳（Eriugena）是爱尔兰的新柏拉图主义哲学家与诗人。他因为译注亚略巴古的伪丢尼修（Pseudo-Dionysius the Areopagite）的著作而广为人知。爱留根纳的思想注重逻辑的完整，常会将神学命题推向逻辑的极端，而违反了西方教会政体和教牧的需要，因为其著作从中世纪直至近代，不断受到教会的谴责。

He wrote a number of works, but is best known today, and had most influence in subsequent centuries, for having translated and made commentaries upon the work of Pseudo-Dionysius.
