波兰王国（波兰语：Królestwo Polskie，俄语：Царство Польское），通常称为波兰会议王国（波兰语：Kongresówka）或俄属波兰。该国在1815年经由维也纳会议成立，在1915年被同盟国用另一个波兰王国取代。该国在本质上是俄国的共主邦联。虽然原则上，波兰王国获得了相当大的正式的政治上的主权，成为了独立国家，但沙皇总体上并不顾及这些限制他们权力的因素，且严格地说，在十一月起义和一月起义后，俄罗斯更是削弱了波兰议会王国的自主权，首先将该国变为俄国的总督区，随后又将该国划分为俄罗斯帝国的几个省。这样，波兰所谓的主权也就不复存在了。

The Kingdom of Poland (Polish:Królestwo Polskie [kruˈlɛstfɔ ˈpɔlskʲɛ]; Russian:Королевство Польское, Царство Польское, Korolevstvo Polskoye, Tsarstvo Polskoye, Russian pronunciation: [kərɐˈlʲɛfstvə ˈpolʲskəje, ˈtsarstvə ˈpolʲskəje], Polish:Carstwo Polskie, translation: Tsardom of Poland), informally known as Congress Poland (Polish:Królestwo Kongresowe [kruˈlʲɛstfɔ kɔnɡrɛˈsɔvɛ] or Russian Poland) was created in 1815 by the Congress of Vienna as a non-sovereign state of the Russian part of Poland connected by personal union with the Russian Empire under the Constitution of the Kingdom of Poland until 1832. Then, it was gradually politically integrated into Russia over the course of the 19th century, made an official part of the Russian Empire in 1867, and finally replaced during the Great War by the Central Powers in 1915 with the theoretically existing Regency Kingdom of Poland.
