Oe with macron (Ө̄ ө̄; italics: Ө̄ ө̄) is a letter of the Cyrillic script.
Oe with macron is used in Selkup to represent a long close-mid front rounded vowel /øː/ and in Uilta to represent long /o~ɵː/.
Until a new alphabet was published in 2016, it was used in Negidal to represent a long close-mid central rounded vowel /ɵː/.
