The Russian alphabet is the script used to write the Russian language. It comes from the Cyrillic script, which was devised in the 9th century for the first Slavic literary language, Old Slavonic. Initially an old variant of the Bulgarian alphabet, it became used in the Kievan Rusʹ since the 10th century to write what would become the modern Russian language.

Russian is an East Slavic language, spoken primarily in Russia. It is the native language of the Russians and belongs to the Indo-European language family. It is one of four living East Slavic languages, and is also a part of the larger Balto-Slavic languages. It was the de facto and de jure official language of the former Soviet Union. Russian has remained an official language in independent Russia, Belarus, Kazakhstan, Kyrgyzstan, and Tajikistan, and is still commonly used as a lingua franca in Ukraine, Moldova, the Caucasus, Central Asia, and to a lesser extent in the Baltic states and Israel.

The Ostromir Gospels of 1056 is the second oldest East Slavic book known, one of many medieval illuminated manuscripts preserved in the Russian National Library.
