長鬚鴞學名Xenoglaux loweryi),又名長鬚鵂鶹,是秘魯亞馬孫大區聖馬丁大區安地斯山脈特有的一種細小貓頭鷹。它們只分佈在海拔1890-2200米的茂密雲林。

長鬚鴞主要呈褐色,腹部及眼眉呈白色。眼睛很大及呈橙褐色。雖然沒有耳羽,其面部的羽毛長於頭部,彷彿有很長的耳羽一般。其名意思為「奇特的貓頭鷹」,就是指它們如此長的面部羽毛。它們一般長13-14厘米,是世界上最細小的貓頭鷹。它們可能是吃昆蟲的。

對於長鬚鴞的所知甚少。曾有三次將它們捕捉的紀錄。在自然環境下很難觀察到它們,最先是於2007年在日間觀察到它們及於夜間錄取了它們的叫聲。[2][3]

由於它們十分稀少,加上分佈地有限及持續的伐林,它們現被列為瀕危[1]估計它們的數量介乎250-1000隻。[4]其分佈位點受到保護,並限制其他物種,如皇領蜂鳥及赭額蟻鶇等的進入。
