Ang Ediakarano (Ingles: Ediacaran /ˌiːdiˈækərən/) na ipinangalan sa Bulunbundking Ediacara ng Timog Australia ang panahong heolohiko ng era na Neoproterosoiko at ng eon na Proterozoic na na nauna sa panahong Cambrian na unang panahon ng era na Paleozoic at eon na Phanerozoic. Ang katayuan nito bilang isang opisyal na panahong heolohiko ay pinagtibay noong 2004 ng International Union of Geological Sciences (IUGS) na gumagawa ritong unang bagong panahong heolohiko na idineklara sa 120 taon. ^[5]^[6]^[7]

Bagaman ang panahong ito ay hinango mula sa Bulubundking Ediacara kung saan ang unang mga natuklasang fossil ng eponimosong biotang Ediakara ay natuklasan noong 1946 ng heologong si Reg Sprigg, ang uring seksiyon ng stata ay matatagpuan sa kama ng Creek na Enorama ^[8] wsa loob ng Gorge na Brachina ^[9] in the Flinders Ranges of South Australia, at 31°19′53.8″S 138°38′0.1″E / 31.331611°S 138.633361°E / -31.331611; 138.633361.
