Sviatopolk II Iziaslavich (1050 – April 16, 1113) was supreme ruler of the Kievan Rus for 20 years, from 1093 to 1113. He was not a popular prince, and his reign was marked by incessant rivalry with his cousin Vladimir Monomakh. Upon his death the Kievan citizens raised a rebellion against the Jewish merchants and Varangian officials who speculated in grain and salt.

Sviatopolk was the son of Iziaslav Iaroslavich by his concubine. Sviatopolk's Christian name was Michael. During his brother Iaropolk's life, Sviatopolk was not regarded as a potential claimant to the Kievan throne. In 1069 he was sent to Polotsk, a city briefly taken by his father from the local ruler Vseslav, and then he spent ten years (1078–88) ruling Novgorod. Upon his brother's death he succeeded him in Turov, which would remain in possession of his descendants until the 17th century.

When Vsevolod Iaroslavich died in 1093, Sviatopolk was acknowledged by other princes as the senior son of Veliki Kniaz and permitted to ascend the Kievan throne. Although he participated in the princely congresses organized by Vladimir Monomakh, he is sometimes charged with encouraging internecine wars among Rurikid princes. For instance, he sided with his cousin David of Volhynia and his son-in-law Bolesław III Wrymouth in capturing and blinding one of Galician princes. He also sided with Vladimir Monomakh in several campaigns against the Kypchaks but was defeated in the Battle of the Stugna River (1093).
