List of constituencies for the Senate of the Republic of Poland

The list of constituencies for the Senate of the Republic of Poland provides an overview of the distribution and numbering of the constituencies (Polish: Okręgi wyborcze) for the election to the Senate of the Republic of Poland since 2011. The current constituency division arose from the change from multi-person constituencies to single-person constituencies and dissolved the constituencies existing used from 2001 to 2011. The most recent constituencies were contested for the first time in the parliamentary elections on 9 October 2011.

Legal basis
The legal basis for Senate constituencies are Articles 260 and 261 of the Election Code (Kodeks wyborczy).

The constituencies for the Senate of the Republic of Poland, the number of which is fixed at 100, should fully encompass Sejm electoral districts and not violate powiats and voivodeship borders. Cities of more than 500 thousand inhabitants can be divided into two or more constituencies. The shape of a constituency is based on the number of residents living in it: ideally, this should be around one hundredth of the total population, but variation between 0.5 and 2.0 multiple of the reference one hundredth is allowed. For the 2011 Polish parliamentary election, the National Electoral Commission (Państwowa Komisja Wyborcza) announced the reference number to be 377,483. Therefore the lower limit for a constituency was 188,742 inhabitants and the upper limit 754,966. The exact layout of the constituencies can be found in Appendix No. 2 (Załącznik nr 2) of the Election Code.

Votes cast abroad (in embassies and consulates) and on Polish ships count towards the 44th constituency per article 14 section 3 of the Election Code which states that all non-domestically cast votes should be included in the count for the Downtown (Śródmieście) district of Warsaw.
