三游洞摩崖，简称三游洞，位于湖北省宜昌市西北7公里的西陵峡口长江左岸的山崖上。2006年5月25日，宜昌市三游洞摩崖被列入第六批全国重点文物保护单位。
相传唐元和十四年(819)，白居易、白行简、元稹三人会于夷陵(今湖北宜昌)，同游洞中，各赋诗一首，并由白居易作《三游洞序》，写在洞壁上，三游洞即由此而得名，这是人们称之为“前三游”。到了宋代，著名文学家苏洵、苏轼(东坡)、苏辙父子三人，也来游洞中，各提诗一首于洞壁之上，人们称之为“后三游”。
三游洞景色奇丽，曾被古人喻为“幻境”。历代途经夷陵(宜昌)的人，大都到此一游，并以楷、隶、行、草各种字体和诗歌、散文、壁画、题记等形式写景抒怀，镌刻于石壁之上。至今洞内外尚存有宋代欧阳修题记、明代重刻之《三游洞序》等各种壁刻和碑文40余件，留下了宝贵的文化史料。
唐宋以来，白居易、元稹、白行简、欧阳修、苏洵、苏轼、苏辙、黄庭坚、陆游等历代游览过三游洞的名人，以及在夷陵任过职的官吏，或题写诗文、或刻碑记事，共作壁刻、碑刻100多件，楷、隶、篆、行、草各体皆备。像清人陆维的隶书壁刻“鬲凡”，陈建候命长女闺瑛用小篆书写的《占合掌岩》巨幅壁刻“合掌岩高石不顽，化工有宝秘形山，辟开混沌蒙窍，露出人间生死关”，均堪称书法上品。
