Svatopluk II or Svätopluk II (Latin: Zentobolchus) was a member of the House of Mojmír and Prince in Moravia (maybe of Nitra) from 894 to 899, as which he strove to control all of Great Moravia.

Their conflict climaxed when Bavarian troops intervened in the winter of 898/899.

He probably died in 906 in fights with the Hungarians, who began to invade the Carpathian Basin in 896.

Historical records contain no mention of Mojmír II, Svatopluk II, or their possible successors in connection with the three battles of Bratislava where the invading tribes defeated the Bavarian army.
