全埃塞俄比亚社会主义运动（阿姆哈拉语拉丁转写：Mela Ethiopia Sosialist Niqinaqē）是埃塞俄比亚的一个政党。该党成立于1968年8月。1970年代，该党曾活跃于埃塞俄比亚政坛。该党和埃塞俄比亚人民革命党是推翻海尔·塞拉西一世的革命的热情支持者。海尔·马里亚姆·门格斯图掌权后，该党以及埃塞俄比亚人民革命党和门格斯图政权产生了严重的意识形态冲突。1976年，这两个政党的支持者与门格斯图的军队发生了暴力冲突。但该党与门格斯图政权的盟友关系一直保持到了1977年。1977年下半年，门格斯图决定取缔该党，该党的领导人先是转入地下，但后来都被逮捕并遭到处决。门格斯图政权还血腥镇压了该党在农村的支持者。

The All-Ethiopia Socialist Movement (in Amharic: Mela Ethiopia Sosialist Niqinaqē, መላ የኢትዮጵያ ሶሲያሊስት ንቅናቄ, MEISON ) is a political party in Ethiopia. A Marxist-Leninist organization, MEISON played an active role in Ethiopian politics during the 1970s. Both it and the Ethiopian People's Revolutionary Party (EPRP) were enthusiastic supporters of the revolution that toppled Emperor Haile Selassie I. However, as Mengistu Haile Mariam rose to power as chairman of the ruling Derg government, conflict began to develop between the two groups, with MEISON aligning itself with Mengistu.
