'''Gliese 581 e''' ({{pron-en|ˈɡliːzə}}) adalah [[planet luar suryaeksoplanet]] keempat yang ditemukan di sekitar [[Gliese 581]], berjarak sekitar 20 tahun cahaya di rasi bintang [[Libra]]. Planet ini ditemukan oleh tim [[Michel Mayor]] dari [[Observatorium Jenewa]] di [[Swiss]]. Penemuan planet ini diumumkan pada tanggal [[21 April]] [[2009]]. Planet ini minimal mempunyai massa sebesar 1,9 [[massa Bumi]] sehingga merupakan planet luar suryaeksoplanet yang massanya paling mendekati [[Bumi]] (per 23 April 2009). Meskipun begitu, suhu udara yang tinggi, ukuran yang kecil, dan radiasi yang kuat dari bintang induknya membuatnya kemungkinan besar tidak memiliki [[atmosfer]].<ref name="hasilan otomatis1">{{cite journal | url=http://obswww.unige.ch/~udry/Gl581_preprint.pdf |author=Mayor et al. |title=The HARPS search for southern extra-solar planets,XVIII.
