Sejm Constituency no. 20

Warsaw II is a Polish parliamentary constituency in the Masovian Voivodeship. It elects twelve members of the Sejm.

The district has the number 20 for elections to the Sejm, and is named after the country's capital city, Warsaw. However, it does not include Warsaw itself, but covers the surrounding counties of Grodzisk Mazowiecki, Legionowo, Nowy Dwór, Otwock, Piaseczno, Pruszków, Warsaw West, and Wołomin.

The constituency is often referred to by media as obwarzanek due to its geographic shape.
