Oe (Cyrillic)
Oe or barred O is a letter of the Cyrillic script.

Oe is used in the alphabets of the Bashkir, Buryat, Kalmyk, Karakalpak, Kazakh, Komi-Yazva, Kyrgyz, Mongolian, Sakha, Selkup, Tatar and Tuvan languages.In Turkic languages, it commonly represents the front rounded vowels // or //. In Kazakh and Karakalpak, it may also express //. In Mongolic languages, it usually represents // or //.

Until a new alphabet was published in 2016, Oe was used to represent // in Negidal.
Oe is most commonly romanized as ; but its ISO 9 transliteration is. In 2018, there were proposals to use as a romanization of Oe in Kazakh, but a year later it was certified as.
The International Phonetic Alphabet uses the identically shaped Latin counterpart, ɵ, to represent the close-mid central [rounded vowel], and sometimes also the mid central rounded vowel.
