Bohuslav (Ukrainian: Богуслав, IPA: [boɦʊˈslɑu̯]; Yiddish: באָסלעוו, romanized: Boslov) is a city on the Ros River in Obukhiv Raion, Kyiv Oblast, Ukraine.

In 1569 Bohuslav was passed to the Polish Crown and in 1620 it received its Magdeburg rights and its city banner.

After withdrawal of the Russian armed forces in 1708 from Poland, Samus continued to self-govern unlawfully in the region.

Samus was left to defend Bohuslav on his own now against the united armies of Russia and Poland (bound by the Treaty of Narva).

After the second partition of Poland the city was passed to the Russian Empire and until 1837 it was a center of Bohuslav county.
