长须棘鲛（学名Cirrhigaleus barbifer），又名长须卷盔鲨或须棘鲛，是棘鲛科下的一种鲨鱼。牠们分布于西太平洋，从日本的本州至澳洲的新南威尔士、新西兰及瓦努阿图的托雷斯群岛，生活在大陆棚及岛基台。牠们最长可以达1.25米。

长须棘鲛的特征是其巨大的触手。牠们可能以海底的鱼类及一些无脊椎动物为食物。牠们是卵胎生的，每胎约有10头幼鲨。

虽然并未有就长须棘鲛的商业渔业，但其肝脏的角鲨烯很丰富。

The mandarin dogfish, Cirrhigaleus barbifer, is a dogfish, a member of the family Squalidae in the order Squaliformes. It is found at depths of 140–650 metres (460–2,130 ft) off southern Japan, ******, and Indonesia (Bali and Lombok). Populations off Australia and New Zealand were formerly included in this species, but in 2007 these were assigned to a new species, C. australis. It is not clear which of these species is involved in other populations from the tropical West Pacific.
