'''足羽龍屬'''（[[屬]]名：''Pedopenna''）是種小型、有[[羽毛]]的[[手盜龍類]][[恐龍]]，化石發現於[[中國]]的[[道虎溝化石層]]。

足羽龍可能比[[始祖鳥]]還要古老，雖然道虎溝化石層的地質年代仍未確定。有些測量認為該地層屬於早[[白堊紀]]，但最近的[[放射性定年法]]顯示該地曾屬於侏羅紀中期末（1億6800萬年前），到[[侏儸紀]]晚期（約1億6400萬年前到1億5200萬年前）之間。

足羽龍的屬名''Pedopenna''指的是牠們[[蹠骨]]上的長[[正羽]]；種名''daohugouensis''則是指[[正模標本]]的發現地[[道虎溝]]<ref name=description>{{Cite journal | doi = 10.1007/s00114-004-0604-y | author = Xu, X., and Zhang, F. | year = 2005 | title = A new maniraptoran dinosaur from China with long feathers on the metatarsus | url = | journal = Naturwissenschaften | volume = 92 | issue = 4| pages = 173–177 | pmid = 15685441 | bibcode=2005NW.....92..173X}}</ref>。

道虎溝足羽龍身長可能約1公尺，或者更小；但因為足羽龍僅有發現後肢[[化石]]，因此很難估計牠們的身長。足羽龍最初被分類於[[近鳥類]]的[[恐爪龍下目]]，近鳥類包含[[鳥翼類]]與牠們的最近親；某些研究人員提出足羽龍屬於鳥翼類，親緣關係接近於現代[[鳥類]]，而離恐爪龍下目較遠<ref name=hone2010>{{cite journal | author = Hone D.W.E., Tischlinger H., Xu X., Zhang F. | editor1-last = Farke | year = 2010 | editor1-first = Andrew Allen | title = The extent of the preserved feathers on the four-winged dinosaur ''Microraptor gui'' under ultraviolet light | url = http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0009223 | journal = PLoS ONE | volume = 5 | issue = 2 | page = e9223 | doi = 10.1371/journal.pone.0009223 | bibcode = 2010PLoSO...5.9223H | access-date = 2012-09-23 | archive-date = 2012-10-04 | archive-url = https://web.archive.org/web/20121004230834/http://www.plosone.org/article/info:doi%2F10.1371%2Fjournal.pone.0009223 | dead-url = no }}</ref>。
