《紅樓夢》是出現於盛清時期的文學鉅著，從內容表面看，本書主要在描繪一個豪門大族成員的生活瑣事，以及家勢的興衰變化，但近年學界普遍認為：賈寶玉即作者的影子，而作者本人雖未趕上家族的全盛時代，但因自幼濡目染豪暑生活，中晚年窮苦潦倒之餘，揉合了回憶錄式的家傳以及自己心目中幻想的完美樂園，而寫成本書。 雖因如此，本書不被認定為寫實小說，不過，書中有很多的情節仍脫不了當代時空環境的影響，而有不少寫實的成份，宗教行為就是其中的一項。本文是藉重宗教學上有關宗教行為的概念，探討書中所涉及的民間巫術、宗教禁忌、祝禱及祭祀，藉以瞭解傳統社會中豪門人士的宗教信仰概況，並試圖置諸中國宗教史的大潮流中，以勾稽明清之際民間信仰風貌之一般。
