'''Ediakara'''<ref>{{dictionary.com|Ediacaran}}</ref> ialah nama sesuatu tempoh geologi yang menjangkaui tempoh masa selama 94 juta tahun, bermula dengan pengakhiran [[Kriogen|Tempoh Kriogen]] pada sekitar 635 juta tahun dahulu (jtd) sehingga bermulanya [[Kambria|Tempoh Kambria]] pada 541 jtd. Ia menandakan berakhirnya Eon [[Proterozoik]] dan bermulanya Eon [[Fanerozoik]]. Tempoh ini diberi nama sempena [[Bukit Ediakara]] di [[Australia Selatan]].<ref name=John2018>{{cite web|url=https://www.britannica.com/science/Ediacaran-Period|title=Ediacaran Period|last=P.

Tempoh Ediakara disahkan sebagai tempoh geologi rasmi oleh [[International Union of Geological Sciences|Kesatuan Sains Geologi Antarabangsa]] (IUGS) pada tahun 2004, menjadikan Ediakara tempoh geologi pertama yang diklasifikasi selepas 120 tahun.<ref name=Knoll2007>{{cite journal|url=https://stratigraphy.org/gssps/files/ediacaran.pdf|title=The Ediacaran Period: a new addition to the geologic time scale|last=H Knoll|first=Andrew|last2=Walter|first2=Malcolm|last3=Narbonne|first3=Guy|last4=Christie-Blick|first4=Nicholas|date=2 Januari 2007|format=pdf|journal=[[Lethaia]]|volume=39|issue=1|doi=10.1080/00241160500409223|  language=en|access-date=3 Ogos 2020}}</ref><ref name=Knoll2004>{{cite journal
