O with macron (О̄ о̄; italics: О̄ о̄) is a letter of the Cyrillic script. In all its forms it looks exactly like the Latin letter O with macron (Ō ō Ō ō).

O with macron are used in the Evenki, Mansi, Nanai, Negidal, Orok, Ulch, Kildin Sami, Selkup, and Chechen languages.

O with macron also appears in the Rusyn language in Ukraine, representing a close allophone of /o/. However, this letter primarily features in materials for beginning readers; the same sound is otherwise represented with the Cyrillic letter O.{{Cite book|author= |date=1999 |title=Материнськый язык: писемниця русинського языка |location=Мукачово |publisher=Общество им.
