Sumerian (Sumerian: 𒅴𒂠, romanized: eme-gir15[a], lit. ''native language'') was the language of ancient Sumer. It is one of the oldest attested languages, dating back to at least 2900 BC. It is a local language isolate that was spoken in ancient Mesopotamia, in the area that is modern-day Iraq.

Akkadian, a Semitic language, gradually replaced Sumerian as the primary spoken language in the area c. 2000 BC (the exact date is debated), but Sumerian continued to be used as a sacred, ceremonial, literary, and scientific language in Akkadian-speaking Mesopotamian states such as Assyria and Babylonia until the 1st century AD.
