Kyrgyz (English: ; autonym: Кыргыз тили, tr. Kyrgyz tili, [qɯɾʁɯz tili]) is a Turkic language of the Kipchak branch spoken in Central Asia. Kyrgyz is the official language of Kyrgyzstan and a significant minority language in the Kizilsu Kyrgyz Autonomous Prefecture in Xinjiang, China and in the Gorno-Badakhshan Autonomous Region of Tajikistan. There is a very high level of mutual intelligibility between Kyrgyz, Kazakh, and Altay. A dialect of Kyrgyz known as Pamiri Kyrgyz is spoken in Afghanistan and Pakistan.

Kyrgyz is also spoken by many ethnic Kyrgyz through the former Soviet Union, Afghanistan, Turkey, parts of northern Pakistan, and Russia.

Kyrgyz was originally written in Göktürk script, gradually replaced by the Perso-Arabic alphabet (in use until 1928 in the USSR, still in use in China). Between 1928 and 1940 a Latin-script alphabet, the Uniform Turkic Alphabet, was used. In 1940, Soviet authorities replaced the Latin script with the Cyrillic alphabet for all Turkic languages on its territory. When Kyrgyzstan became independent following the Soviet Union's collapse in 1991, a plan to adopt the Latin alphabet became popular. Although the plan has not been implemented, it remains in occasional discussion.
