Sirius (Russian: Сириус) is an urban locality (an urban-type settlement) in Krasnodar Krai, Russia.

[2] Sirius is located on the Black Sea coast, between the Mzymta in the northwest and the Psou on the southeast.

From the inland site, Sirius is roughly bounded by A147 highway connecting Dzhubga via Tuapse and Sochi with the Russian border.

It was first subordinated to Sochi, and eventually on 22 December 2020 a law designating Sirius as the first ever federal territory was adopted and signed.

[2] The settlement contains an eponymous education center and is expected to grow into a large high-tech campus.
