The Senate (Polish: Senat) is the upper house of the Polish parliament, the lower house being the Sejm. The history of the Polish Senate stretches back over 500 years; it was one of the first constituent bodies of a bicameral parliament in Europe and existed without hiatus until the final partition of the Polish state in 1795. The contemporary Senate is composed of 100 senators elected by a universal ballot and is headed by Marshal of the Senate (Marszałek Senatu). The incumbent Marshal of the Senate is Tomasz Grodzki. Following a brief period of existence under the Second Polish Republic, the Senate was again abolished by the authorities of the Polish People's Republic. It was not re-established until the collapse of the communist government and reinstatement of democracy in Poland in 1989. The Senate is based in Warsaw and is located in a building which forms part of the Sejm Complex on Wiejska Street, in close proximity to the Three Crosses Square and Ujazdów Castle.

The Sejm (English: Seym, Polish: [sɛjm] (listen)), officially known as the Sejm of the Republic of Poland (Polish: Sejm Rzeczypospolitej Polskiej), is the lower house of the bicameral parliament of Poland. The Sejm has been the highest governing body of the Third Polish Republic since the transition of government in 1989. Along with the upper house of parliament, the Senate, it forms the national legislature in Poland. The Sejm is composed of 460 deputies (singular deputowany or poseł – "envoy") elected every four years by a universal ballot. The Sejm is presided over by a speaker called the "Marshal of the Sejm" (Marszałek Sejmu). In the Kingdom of Poland, the term "Sejm" referred to an entire two-chamber parliament, comprising the Chamber of Deputies (Polish: Izba Poselska), the Senate and the King. It was thus a three-estate parliament. The 1573 Henrician Articles strengthened the assembly's jurisdiction, making Poland a constitutional elective monarchy. Since the Second Polish Republic (1918–1939), "Sejm" has referred only to the larger house of the parliament.
