'''Mac OS Cyrillic''' is a [[character encoding]] used on [[Apple Macintosh]] computers to represent texts in the [[Cyrillic script]].

The original version lacked the letter [[Ґ]], which is used in [[Ukrainian language|Ukrainian]], although its use was limited during the Soviet era to regions outside Ukraine. The closely related [[Macintosh Ukrainian encoding|MacUkrainian]] resolved this, differing only by replacing two less commonly used symbols with its uppercase and lowercase forms. The [[euro sign]] update of the Mac OS scripts incorporated these changes back into MacCyrillic.

Other related code pages include [[Mac OS Turkic Cyrillic]] and [[Mac OS Barents Cyrillic]], introduced by [[Michael Everson]] in fonts for languages unsupported by standard MacCyrillic.
