提格利尼亚语，又译蒂格里亚语（ትግርኛ, tigriññā）是一种闪语族的语言，主要是位于厄立特里亚中部的提格雷-提格雷尼亚语族（Tigray-Tigrinya people，一般被称为“提格利尼亚人”“Tigrinya people”）使用，亦是厄立特里亚两种主流语言之一。在埃塞俄比亚的提格里州是当地的官方语言，并为从当地移居到外地的居民，包括部分现在以色列定居的贝塔以色列部落（Beta Israel）日常所使用的语言。

Tigrinya, often written as Tigrigna /tɪˈɡriːnjə/ (ትግርኛ Tigriññā) is a member of the Semitic branch of the Afroasiatic languages. It is spoken by ethnic Tigray-Tigrinya people in the Horn of Africa. Tigrigna speakers primarily inhabit the Tigray Region in northern Ethiopia (57%), where its speakers are called Tigrawot (feminine Tigrāweyti, male Tigraway, plural Tegaru), as well as the contiguous borders of southern and central Eritrea (43%), where speakers are known as the Tigrigna. Tigrigna is also spoken by groups of emigrants from these regions, including some Beta Israel.
