埃塞俄比亚语言联盟是Charles A. Ferguson(1970, 1976)提出的语言联盟，包含一些音系和形态音素学上相近的语言，分布在埃塞俄比亚和厄立特里亚，包括埃塞俄比亚闪米特语支、库希特语族和奥摩语族的一些语言，而不包括尼罗-撒哈拉语系语言。 

其他学者之后指出了语言联盟内部一些有共享特征的小区域。(Appleyard 1989, Breeze 1988, Sasse 1986, Tosco 1994, Wedekind 1989)

最引人注意的特征之一是动词“说”可用于不可屈折词根的屈折词缀(Appleyard 2001, Cohen et al. 2002)。Hayward指出，词汇化的模式在整片语区也很相似(1999, 2000)，Treis提供了更多例子(2010)。

Tosco早先说这个语言联盟的成立是“板上钉钉的”(1994:415)，但他后来又大加批判了Ferguson的原文(2000)。他总结说，埃塞俄比亚语言联盟并不能成立，并认为Ferguson的论文反映了当时埃塞俄比亚民族主义的政治导向，可见于Donald N. Levine的书《大埃塞俄比亚：多民族社会的演化》。

Baye Yiman发现埃塞俄比亚语言联盟在语用学上的相似(1997)。

Güldemann提出，埃塞俄比亚及其西部、西北部的语言普遍使用相似的助动词。相似地，Cohen、Simeone-Senelle、Vanhove都观察到“说”和“做”两个动词的语法化，并将其视作东非地区的区域特征。

Wu Tong观察到埃塞俄比亚语言联盟特有的前置关系从句。

Tolemariam Fufa Teso对语言联盟内的各种语言进行了大规模比较研究。

该语言联盟的存在与否仍有争议。
