'''Gliese 581 c''' ({{pronEng|ˈgliːzə}}), juga disebut '''HO Librae c''', '''Wolf 562 c''', dan '''HIP 74995 c''', adalah [[bumi super]] atau [[planet ekstrasurya]] yang mengorbit [[bintang]] [[katai merah]] [[Gliese 581]].<ref name="space.com">{{cite web | url=http://www.space.com/scienceastronomy/070424_hab_exoplanet.html | title=Major Discovery: New Planet Could Harbor Water and Life | last=Than | first=Ker | date=[[2007-04-24]] | publisher=space.com | accessdate=2007-04-29}}</ref> Kemungkinan planet ini berada pada [[zona layak huni]], di mana [[suhu]] permukaannya memungkinkan adanya [[air]]. Planet ini berjarak 20,4 [[tahun cahaya]] (193 [[triliun]] [[km]]) dari Bumi dan terletak di [[rasi bintang]] [[Libra]]. Gl 581, atau Gliese 581, merupakan bintang ke 581 dalam urutan [[Katalog Gliese]]. Katalog tersebut dibuat oleh Gliese, diterbitkan pada tahun 1969 dan diperbaharui tahun 1991 oleh Gliese dan Jahreiss.
