Architecture in Kievan Rus' was centered on Kiev and Novgorod. The architecture of Kievan Rus' is the earliest period of both Russian and Ukrainian architecture, using the foundations of Byzantine culture but with use of innovations and architectural features. Most surviving architecture from this period consists of Russian Orthodox churches, or parts of the gates and fortifications of cities.

After the disintegration of Kievan Rus' and the Mongol invasion in the first half of the 13th century, the architectural tradition of Kievan Rus' architecture continued in the principalities of Novgorod, Vladimir-Suzdal, and Galicia-Volhynia. It had a direct influence on later Russian, Ukrainian, and Belarusian architecturural styles.
