Silesian Voivodeship (Polish: województwo śląskie [vɔjɛˈvut͡stfɔ ˈɕlɔ̃skʲɛ] ) is a voivodeship, or province, in southern Poland centered on the historic region known as Upper Silesia (Górny Śląsk), with Katowice serving as its capital.

Despite the Silesian Voivodeship's name, most of the historic Silesia region lies outside the present Silesian Voivodeship – divided among Lubusz, Lower Silesian, and Opole Voivodeships. The eastern half of Silesian Voivodeship (and, notably, Częstochowa in the north) was historically part of Lesser Poland.

It is the most densely populated voivodeship in Poland. Within the area of 12,300 square kilometres, there are almost 5 million inhabitants. It is also the largest urbanised area in Central and Eastern Europe. In relation to economy, over 13% of Poland's gross domestic product (GDP) is generated here, making the Silesian Voivodeship one of the wealthiest provinces in the country.

The first Silesian Voivodeship was created in the Second Polish Republic. It had a much wider range of autonomy than other contemporary Polish voivodeships, and it covered all the historical lands of Upper Silesia which ended up in Interwar period Poland. Among these were Katowice, Rybnik, Pszczyna, Wodzisław Śląski, Żory, Mikołów, Tychy, Chorzów, Tarnowskie Góry, Miasteczko Śląskie, Woźniki, Lubliniec, Cieszyn, Skoczów, and Bielsko. This Voivodeship did not include – as opposed to the present one – lands and cities of old pre-Partition Polish–Lithuanian Commonwealth. Among the last ones the Southern part was included in Kraków Voivodeship Żywiec, Wilamowice, Biała Krakowska and Jaworzno), and the North Western part Będzin, Dąbrowa Górnicza, Sosnowiec, Częstochowa, Myszków, Szczekociny, Zawiercie, Sławków) belonged to Kielce Voivodeship.

During the invasion of Poland, German troops committed several massacres of Polish civilians and defenders, including children, and Jews within the territory of the current Silesian Voivodeship, including the largest at Parzymiechy, Albertów, Częstochowa, Katowice, Będzin, and Sławków. During the subsequent occupation, on 8 October 1939, Hitler published a decree called, "About division and administration of Eastern Territories". A Silesian Province (Gau Schlesien) was created, with a seat in Breslau (Wrocław). It consisted of four districts: Kattowitz, Oppeln, Breslau and Liegnitz.

The following counties were included in Kattowitz District: Kattowitz, Königshütte, Tarnowitz, Beuthen Hindenburg, Gleiwitz, Freistadt, Teschen, Biala, Bielitz, Saybusch, Pleß, Sosnowitz, Bendzin and parts of the following counties: Kranau, Olkusch, Riebnich and Wadowitz. However, according to Hitler's decree from 12 October 1939 about establishing General Government, Częstochowa belonged to GG.

In 1941 the Silesian Province (Provinz Schlesien) underwent new administrative division and as a result Upper Silesian Province was created (Provinz Oberschlesien):

• Kattowitz District (Regierungsbezirk Kattowitz) – entire Silesian Voivodeship without Lubinitz county, Bendzin County, part of Olkusch county, Biala county, Saybusch and parts of Kranau and Wadowitz counties.
• Oppeln District (Regierungsbezirk Oppeln) – Lubinitz county and parts of Tschenstochau and Warthenau counties.

Nazi Germany established and operated a network of Polenlager forced labour camps and multiple subcamps of the Auschwitz concentration camp in the area.

After the War during 1945–1950 there existed a Silesian Voivodeship, commonly known as Śląsko-Dąbrowskie Voivodeship, which included a major part of today's Silesian Voivodeship. In 1950 Śląsko-Dąbrowskie Voivodeship was divided into Opole and Katowice Voivodeships. The latter had borders similar to the borders of modern Silesian Voivodeship.

The present Silesian Voivodeship was formed on 1 January 1999 from the following voivodeships of the previous administrative division:

• Katowice Voivodeship excluding some gminas and powiats
• Bielsko-Biała Voivodeship excluding some gminas and powiats
• Częstochowa Voivodeship excluding some gminas and powiats

The Silesian Voivodeship borders both the Moravian-Silesian Region (Czech Republic), Žilina Region (Slovakia) to the south. It is also bordered by four other Polish voivodeships: those of Opole (to the west), Łódź (to the north), Świętokrzyskie (to the north-east), and Lesser Poland (to the east).

The region includes the Silesian Upland (Wyżyna Śląska) in the centre and north-west, and the Krakowsko-Częstochowska Upland (Jura Krakowsko-Czestochowska) in the north-east. The southern border is formed by the Beskidy Mountains (Beskid Śląski and Beskid Żywiecki).

The current administrative unit of Silesian Voivodeship is just a fraction of the historical Silesia which is within the borders of today's Poland (there are also fragments of Silesia in the Czech Republic and Germany). Other parts of today's Polish Silesia are administered as the Opole, the Lower Silesian Voivodeships and the Lubusz Voivodeship. On the other hand, a large part of the current administrative unit of the Silesian Voivodeship is not part of historical Silesia (e.g., Częstochowa, Zawiercie, Myszków, Jaworzno, Sosnowiec, Żywiec, Dąbrowa Górnicza, Będzin and east part of Bielsko-Biała, which were historically parts of Lesser Poland).

Silesian Voivodeship has the highest population density in the country (379 people per square kilometre, compared to the national average of 124). The region's considerable industrialisation gives it the lowest unemployment rate nationally (6.2%). The Silesian region is the most industrialized and the most urbanized region in Poland: 78% of its population live in towns and cities.

Both the northern and southern parts of the voivodeship are surrounded by a green belt. Bielsko-Biała is enveloped by the Beskidy Mountains which are popular with winter sports fans. It offers over 150 ski lifts and 200 kilometres of ski routes. More and more slopes are illuminated and equipped with artificial snow generators. Szczyrk, Brenna, Wisła and Ustroń are the most popular winter mountain resorts. Rock climbing sites can be found in Jura Krakowsko-Czestochowska. In the south-western part of the voivodeship are parks and old monasteries (Rudy Raciborskie, Wodzisław Śląski). Along the Oder River are interesting natural reserves and places for swimming during the summer.

There are numerous castles and palaces in the voivodeship, including the medieval castles of the Piast dynasty in Będzin, Gliwice, Racibórz, and the castles forming the Trail of the Eagle's Nests, including at Bobolice, Mirów, Ogrodzieniec and Olsztyn. The best-preserved palaces include those at Brynek, Kłobuck, Koniecpol, Kończyce Wielkie, Pławniowice, Sosnowiec and Złoty Potok.

Often visited is the Black Madonna's Jasna Góra Sanctuary in Częstochowa – the annual destination of over 4 million pilgrims from all over the world. Another local pilgrimage destination is the Basilica of St. Mary and St. Bartholomew in Piekary Śląskie. Other notable historic churches include the St. Nicholas' Chapel in Cieszyn, a Romanesque rotunda, depicted on the 20 złotych note, and the St. Mary Magdalene Church in Cieszyn, which contains a number of sarcophagi of Polish dukes from the Piast dynasty.

There are three spa towns in the voivodeship: Goczałkowice-Zdrój, Jastrzębie-Zdrój, and Ustroń.

With its more than two centuries of industrial history, the region has a number of technical heritage memorials. These include narrow and standard gauge railways, coal and silver mines, and shafts and their equipment from the 19th and 20th centuries. The historic coal mine complex in Zabrze is listed as a Historic Monument of Poland, and the Historic Silver Mine in Tarnowskie Góry is listed as both a UNESCO World Heritage Site and Historic Monument of Poland.

There are numerous memorials to Polish uprisings against foreign rule, including the January Uprising of 1863–1864 and Silesian Uprisings of 1919–1921, and Świętochłowice hosts the Silesian Uprisings Museum.

There are numerous World War II memorials in the voivodeship, including at the sites of Nazi massacres of Poles and Jews, and at the sites of former Nazi German forced labour camps and prisons. The Gliwice Radio Tower and Katowice Parachute Tower are local symbols of German provocation and Polish resistance during the war, respectively.

Due to its industrial and urban nature, the voivodeship has many cities and large towns. Of Poland's 40 most-populous cities, 12 are in Silesian Voivodeship. 19 of the cities in the voivodeship have the legal status of city-county (see powiat). In all, it has 24 cities and 47 towns, listed below in descending order of population (as of 2019):

The gross domestic product (GDP) of the province was 61 billion € in 2018, accounting for 12.3% of the Polish economic output. GDP per capita adjusted for purchasing power was 22,200 € or 74% of the EU27 average in the same year. The GDP per employee was 83% of the EU average. Silesia Voivodship is the province with the fourth highest GDP per capita in Poland.

The Silesian voivodship is predominantly an industrial region. Most of the mining is derived from one of the world's largest bituminous coalfields of the Upper Silesian Industrial District (Górnośląski Okręg Przemysłowy) and the Rybnik Coal District (Rybnicki Okręg Węglowy) with its major cities Rybnik, Jastrzębie-Zdrój, Żory and Wodzisław Śląski. Lead and zinc can be found near Bytom, Zawiercie and Tarnowskie Góry; iron ore and raw materials for building – near Częstochowa. The most important regional industries are: mining, iron, lead and zinc metallurgy, power industry, engineering, automobile, chemical, building materials and textile. In the past, the Silesian economy was determined by coal mining. Now, considering the investment volume, car manufacturing is becoming more and more important. The most profitable company in the region is Fiat Auto-Poland S.A. in Bielsko-Biała with a revenue of PLN 6.2 billion in 1997. Recently a new car factory has been opened by GM Opel in Gliwice. There are two Special Economic Zones in the area: Katowice and Częstochowa. The voivodship's economy consists of about 323,000, mostly small and medium-sized, enterprises employing over 3 million people. The biggest Polish steel-works "Huta Katowice" is situated in Dąbrowa Górnicza.

The unemployment rate stood at 3.9% in 2017 and was lower than the national average.

Katowice International Airport (in Tarnowskie Góry County) is used for domestic and international flights, with the other nearby airports being John Paul II International Airport Kraków-Balice. The Silesian agglomeration railway network has the largest concentration in the country.

The voivodship capital enjoys good railway and road connections with Gdańsk (motorway A1) and Ostrava (motorway A1), Kraków (motorway A4), Wrocław (motorway A4), Łódź (motorway A1) and Warsaw. It is also the crossing point for many international routes like E40 connecting Calais, Brussels, Cologne, Dresden, Wrocław, Kraków and Kyiv and E75 from Scandinavia to the Balkans. A relatively short distance to Vienna facilitates cross-border co-operation and may positively influence the process of European integration.

Linia Hutnicza Szerokotorowa (known by its acronym LHS, English: Broad gauge metallurgy line) in Sławków is the longest broad gauge railway line in Poland. The line runs on a single track for almost 400 km from the Polish-Ukrainian border, crossing it just east of Hrubieszów. It is the westernmost broad gauge railway line in Europe that is connected to the broad gauge rail system of the countries of the former Soviet Union.

Large part of the Upper Silesia conurbation features the Silesian Interurbans, the longest tram network in Poland, and one of the largest in the world. Bus and tram transport in and around Katowice and surrounding cities is managed by the Metropolitan Transport Authority (ZTM) since 2019.

There are eleven public universities in the voivodship. The biggest university is the University of Silesia in Katowice, with 43,000 students. The region's capital boasts the Medical University, The Karol Adamiecki University of Economics in Katowice, the University of Music in Katowice, the Physical Education Academy and the Academy of Fine Arts. Częstochowa is the seat of the Częstochowa University of Technology and Pedagogic University. The Silesian University of Technology in Gliwice is nationally renowned. Bielsko-Biała is home of the Technical-Humanistic Academy. In addition, 17 new private schools have been established in the region.

The Silesian voivodeship's government is headed by the province's voivode (governor) who is appointed by the Polish Prime Minister. The voivode is then assisted in performing his duties by the voivodeship's marshal, who is the appointed speaker for the voivodeship's executive and is elected by the sejmik (provincial assembly). The current voivode of Silesia is Jarosław Wieczorek, whilst the present marshal is Wojciech Saługa.

The Sejmik of Silesia consists of 48 members.
