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, although its use was limited during the Soviet era to regions outside Ukraine. The closely related 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.
