扇羽鰓屬（學名：），又名扇鰓海蛞蝓屬，是裸鰓目枝鰓亞目之下的一個海蛞蝓的屬、海洋腹足綱軟體動物扇羽鰓科的成員。

分類歷史
扇羽鰓屬由Gray於1850年建立，模式種為Flabellina affinis and characterised by the  being arranged on peduncles and the s being annulate. Many species were added by subsequent authors. In 1981 the genus  was merged under the older name Flabellina as despite a large range of morphological characters in the 64 species of Flabellinidae and  known at that time, no clear distinction could be found to separate the species into the two genera. In 2017 an integrative study of the 71 species then considered to be included in Flabellina redistributed the species into seven families and 26 genera.

生物學
如同其他蓑海牛裸鰓動物物種那樣，本屬物種在吃掉刺胞動物後，能將牠們的刺絲胞儲存在自身背部的角突裡。
