迈锡尼希腊语是希腊语的已知最古老的形式，多利亚人入侵前，在迈锡尼时期（公元前16至前12世纪）使用于希腊大陆和克里特岛上。它保存在线形文本B写的题字中，这种文本是公元前14世纪前在克里特岛上发明的。这种题字的多数实例都在克里特岛中部的克诺索斯和伯罗奔尼撒半岛西南部的Pylos所发现的泥板上。这种语言以首次发掘出来的地方迈锡尼命名。

这些泥板长时间无法破解，所有可能的语言都尝试过了，直至迈克尔·文特里斯等在1953年通过证明这门语言是希腊语的早期形式的证据优势而破解了这种文本。

在泥板上文本多数是列表和清单。没有幸存的散文叙述，更少有神话和诗歌。但从这些记录中仍可瞥见关于使用它们的人和在所谓希腊黑暗时代前夕的迈锡尼时代的很多事情。

Mycenaean Greek is the most ancient attested form of the Greek language, used on the Greek mainland, Crete and Cyprus in the Mycenaean Greece (16th to 12th centuries BCE), before the hypothesised Dorian invasion which was often cited as the terminus post quem for the coming of the Greek language to Greece. The language is preserved in inscriptions in Linear B, a script first attested on Crete before the 14th century. Most instances of these inscriptions are on clay tablets found in Knossos in central Crete, and in Pylos in the southwest of the Peloponnese. Other tablets have been found at Mycenae itself, Tiryns and Thebes and at Chania in Western Crete. The language is named after Mycenae, one of the major centres of Mycenaean Greece.
