Bohuslav (Ukrainian: Богуслав, Yiddish: באָסלעוו, romanized: Boslov) is a city on the Ros River in Obukhiv Raion, Kyiv Oblast, Ukraine. It hosts the administration of Bohuslav urban hromada, one of the hromadas of Ukraine. Population: 15,789 (2022 estimate); 17,135 (2001).

It is known as Boslov by some of its Yiddish speaking residents and Boguslav (by the Russophones).

The city's year of establishment and source of name is uncertain. It is mentioned by Hypatian Codex as earlier as 1032 which is assumed as the year of establishment. In official documents it is mentioned as earlier as 1195 when Bohuslavl was handed over by the Grand Prince of Kyiv Rurik II to the Grand Prince of Vladimir-Suzdal Vsevolod III who preceded him on Kyivan throne several years earlier.

In 1240 Bohuslav was destroyed by the Mongol invasion. In 1362 it was liberated by forces of the Grand Duchy of Lithuania, Ruthenia, and Samogitia. In 1569 Bohuslav was passed to the Polish Crown and in 1620 it received its Magdeburg rights and its city banner. Since 1591 Bohuslav belonged to Janusz Ostrogski, the voivode of Volhynia. From 1648 to 1667 it was part of the Cossack Hetmanate and after the Treaty of Andrusovo was once again returned to Poland. In 1685 it was occupied by Samiylo Samus whom Ivan Mazepa appointed the appointed Hetman of Right-bank Ukraine when Poland allowed to restore cossacks' liberties.

Since that time and until 1704 Bohuslav became a residence of the appointed Hetman. In 1704 Samus surrendered his authority to Mazepa. After withdrawal of the Russian armed forces in 1708 from Poland, Samus continued to self-govern unlawfully in the region. In 1711 he joined forces with Pylyp Orlyk, however after number of unsuccessful storms of Bila Tserkva, Orlyk withdrew to Moldova. Samus was left to defend Bohuslav on his own now against the united armies of Russia and Poland (bound by the Treaty of Narva). In 1712 Samus was arrested and exiled to Siberia. Bohuslav regiment was liquidated and the city was returned once again under the Polish administration.

After the second partition of Poland the city was passed to the Russian Empire and until 1837 it was a center of Bohuslav county. The county was restored once again after the establishment of the Soviet regime in 1919 and 1923 it was transformed into the Bohuslav Raion.

It had a large Jewish community. According to the 1897 census, on a total of 11,372 inhabitants, 7445 people were Jews whose community was destroyed in the Holocaust.

Until 18 July 2020, Bohuslav was the administrative center of Bohuslav Raion. The raion was abolished that day as part of the administrative reform of Ukraine, which reduced the number of raions of Kyiv Oblast to seven. The area of Bohuslav Raion was split between Bila Tserkva and Obukhiv Raions, with Bohuslav being transferred to Obukhiv Raion.
