洛芬（Lofn），在北欧神话中，是女神弗丽嘉（Frigg）的侍女之一。一般皆认为她的侍女都是弗丽嘉部份性格的化身之一。

洛芬是爱的女神，通常和另一个爱的女神修芬（Sjofn）一起出现。她是一名相当温柔的女神，主要是守护被禁止的爱情。其名字意思是「赞许」（Permission）。她得到弗丽嘉赐与的权利，可以让难以结合的男女达成心愿。

In Norse mythology, Lofn (Old Norse, possibly "comforter,") "the comforter, the mild," or "loving" is a goddess. Lofn is attested in the Prose Edda, written in the 13th century by Snorri Sturluson and in kennings found in skaldic poetry. In the Prose Edda, Lofn is described as gentle in manner and as an arranger of marriages, even when they have been forbidden. Scholars have proposed theories about the implications of the goddess.
