There are also two breakaway states bordering Russia, namely Abkhazia and South Ossetia. The country has an internationally recognized land border running {{convert|22407|km|mi|0}} in total, and has the second-longest land border of any country in the world, after China ({{convert|22457|km|mi|0}}{{Citation |title=China|date=2022-10-12 |url=https://www.cia.gov/the-world-factbook/countries/china/#geography |work=The World Factbook |publisher=Central Intelligence Agency |language=en |access-date=2022-10-14}}).

The borders of the Russian Federation (formerly the Russian SFSR) were mostly drawn since 1956 (save for minor border changes, e.g., with China), and have remained the same after the dissolution of the Soviet Union. In 2014, Russia annexed Ukraine's Crimean peninsula in a move that remains internationally unrecognized which altered de facto borders with Ukraine. In 2022, Russia further annexed Donetsk, Kherson, Luhansk and Zaporizhzhia oblasts further changing de facto borders with Ukraine.
