Lublin Voivodeship (Polish: województwo lubelskie [vɔjɛˈvut͡stfɔ luˈbɛlskʲɛ] ^ⓘ) is a voivodeship (province) of Poland, located in the southeastern part of the country, with its capital being the city of Lublin.

The region is named after its largest city and regional capital, Lublin, and its territory is made of four historical lands: the western and central part of the voivodeship, with Lublin itself, belongs to Lesser Poland, the eastern part of Lublin Area belongs to Cherven Cities/Red Ruthenia, and the northeast belongs to Polesie and Podlasie. Lublin Voivodeship borders Subcarpathian Voivodeship to the south, Świętokrzyskie Voivodeship to the south-west, Masovian Voivodeship to the west and north, Podlaskie Voivodeship along a short boundary to the north, Belarus (Brest Region) and Ukraine (Lviv and Volyn Regions) to the east. The region's population as of 2024 was 1,996,440. It covers an area of 25,155 square kilometres (9,712 sq mi).

The Polish historical region that encompasses Lublin, and approximates Lublin Voivodeship as it was before the Partitions of Poland, is known as Lubelszczyzna. Provinces centred on Lublin have existed throughout much of Poland's history; for details see the section below on Previous Lublin Voivodeships. Cities and towns of greatest historic importance are Lublin, Chełm, Kazimierz Dolny and Zamość. Lublin hosted several sessions of the Polish Parliament, including the session which established the Polish–Lithuanian Commonwealth (see Union of Lublin), and was the seat of the Crown Tribunal for the Lesser Poland Province, the highest appeal court in the Kingdom of Poland, and Parczew also hosted one session of the Polish Parliament. Horodło was the place of signing of the Polish–Lithuanian Union of Horodło, predating the Union of Lublin.

In the 17th century, there were sizeable Scottish communities in Lublin and Zamość, and also a smaller one in Opole Lubelskie. Lublin and Zamość also hosted Armenian minorities.

The industry of the region was greatly expanded as part of the Central Industrial Region of Poland.

The region was, before World War II, one of the world's leading centres of Judaism. Before the middle of the 16th century, there were few Jews in the area, concentrated in Lublin, Kazimierz Dolny, and perhaps Chełm; but the founding of new private towns led to a large movement of Jews into the region to develop trade and services. Since these new towns competed with the existing towns for business, there followed a low-intensity, long-lasting feeling of resentment, with failed attempts to limit the Jewish immigration. The Jews tended to settle mostly in the cities and towns, with only individual families setting up businesses in the rural regions; this urban/rural division became another factor feeding resentment of the newly arrived economic competitors. By the middle of the 18th century, Jews were a significant part of the population in Kraśnik, Lubartów and Łęczna.

By the 20th century, Jews represented greater than 70% of the population in eleven towns and close to 100% of the population of Łaszczów and Izbica. From this region came both religious figures such as Mordechai Josef Leiner of Izbica, Chaim Israel Morgenstern of Puławy, and Motele Rokeach of Biłgoraj, as well as famous secular author Israel Joshua Singer. Israel's brother, the Nobel prize winner Isaac Bashevis Singer, was not born in Biłgoraj but lived part of his life in the city. The "Old Town" of the city of Lublin contained a famous yeshiva, Jewish hospital, synagogue, cemetery, and kahal, as well as the Grodzka Gate (known as the Jewish Gate).

Before the war, there were 300,000 Jews living in the region, which became the site of the Majdanek concentration camp, Bełżec extermination camp and Sobibór extermination camp as well as several labour camps (Trawniki, Poniatowa, Budzyn, Puławy, Zamość, Biała Podlaska, and the Lublin work camps Lipowa 7 camp, Flugplatz, and Sportplatz) which produced military supplies for the Wehrmacht and Luftwaffe. This was once one of the biggest forced labour centres in German-occupied Europe, with approximately 45,000 Jewish prisoners. After the war, the few surviving Jews largely left the area; today there is some restoration of areas of Jewish historical interest, and a surge of tourism by Jews seeking to view their families' historical roots.
