Podlaskie Voivodeship (Polish: Województwo podlaskie [vɔjɛˈvut͡stfɔ pɔˈdlaskʲɛ] ) is a voivodeship (province) in northeastern Poland. The name of the province refers to the historical region of Podlachia (in Polish, Podlasie), and part of its territory corresponds to that region. The capital and largest city is Białystok.

It borders on Masovian Voivodeship to the west, Warmian-Masurian Voivodeship to the northwest, Lublin Voivodeship to the south, the Belarusian oblasts of Grodno and Brest to the east, the Lithuanian Counties of Alytus and Marijampolė to the northeast, and the Kaliningrad Oblast of Russia to the north.

The province was created on 1 January 1999, pursuant to the Polish local government reforms adopted in 1998, from the former Białystok and Łomża Voivodeships and the eastern half of the former Suwałki Voivodeship.

The voivodeship takes its name from the historic region of Poland called Podlasie, or in Latin known as Podlachia.

There are two opinions regarding the origin of the region's name. People often derive it from the Proto-Slavic les or las, meaning "forest", i.e., it is an area "by the wood(s)" or an "area of forests", which would bring Podlasie close in meaning to adjacent Polesia. This theory has been questioned, as it does not properly take into consideration the vowel shifts "a" > "e" > "i" in various Slavic languages (in fact, it mixes vowels from different languages). Heavily wooded Podlaskie is home to the primeval Białowieża Forest and National Park, the habitat of the European wisent bison and tarpan.

A second view holds that the term comes from the expression pod Lachem, i.e., "under the Poles" (see: Lechia). Some claim it to mean "under Polish rule", which does not seem historically sound, as the area belonged to the Grand Duchy of Lithuania until 1569, and the southern part of it—until 1795.

A better variant of the latter theory holds that the name originates from the period when the territory was within the Trakai Voivodeship of the Grand Duchy of Lithuania, along the border with Mazovia Province, primarily a fief of the Poland of the Piasts, and later part of the Kingdom of Poland of the Jagiellons. Hence pod Lachem would mean "near the Poles", "along the border with Poland". The Lithuanian name of the region, Palenkė, has exactly this meaning.

The voivodeship was created on January 1, 1999, out of the former Białystok and Łomża Voivodeships and the eastern half of the former Suwałki Voivodeship, pursuant to the Polish local government reforms adopted in 1998.

It has a varied landscape, shaped in the north by Baltic glaciation, the rest by Middle Poland glaciation. The highest peaks are in the north (Rowelska Top - 298 m), where the landscape is dominated by a hilly lake district. Lakeland: Zachodniosuwalskie, Wschodniosuwalskie, Ełckie) and Sandrowy lake district (Augustów Plain) in the central and southern pre-glacial plains prevail (plateaus: Kolneńska, Białystok, Wysokomazowiecka, Drohiczynska, Sokólskie Hills, Międzyrzecko łomżyński, Plain Bielsko), varied in topography with small basins and river valleys. Kurpie lies on the west edge of the outwash plains. Sand, gravel, clay, moraine, and in the valleys and basins of the rivers silt, sand and river peat predominate on the surface.

The vast forests (Białowieża, Augustów, Knyszyń, Kurpiowska), some of which are the only ones in Europe to have retained their original character, contain a unique wealth of flora and fauna. The vegetation of the region is extremely diverse, which contributes to the richness of the animal world. Visitors can also see moose, wolves, lynx and bison living in the Białowieża Forest and Knyszyń Forest.

Podlaskie has the lowest population density of the sixteen Polish voivodeships, and its largely unspoiled nature is one of its chief assets. Around 30% of the area of the voivodeship is under legal protection. The Polish part of the Białowieża Forest biosphere reserve (also a World Heritage Site) is in Podlaskie. There are four National Parks (Białowieża, Biebrza, Narew and Wigry), three Landscape Parks (Knyszyń Forest, Łomża and Suwałki), 88 nature reserves, and 15 protected landscape areas. The voivodeship constitutes a part of the ecologically clean area known as "the Green Lungs of Poland".

Podlaskie has a Warm Summer Continental or Hemiboreal climate (Dfb) according to the Köppen climate classification system, which is characterized by warm temperatures during summer and long and frosty winters. It is substantially different from most of the other Polish lowlands. The region is one of the coldest in Poland, with the average temperature in January being −5 °C (23 °F). The average temperature in a year is 7 °C (45 °F). The number of frost days ranges from 50 to 60, with frost from 110 to 138 days and the duration of snow cover from 90 to 110 days. Mean annual rainfall values oscillate around 550 millimetres (21.7 in), and the vegetation period lasts 200 to 210 days.

Podlaskie is the coldest region of Poland, located in the very northeast of the country near the border with Belarus and Lithuania. The region has a continental climate which is characterized by high temperatures during summer and long and frosty winters. The climate is affected by the cold fronts which come from Scandinavia and Siberia. The average temperature in the winter ranges from -15 °C (5 °F) to -4 °C (24.8 °F).

One of the cities located in Podlaskie - Suwalki - is called as The Polish North Pole, due to it is coldest temperature average around Poland.

Podlaskie Voivodeship is divided into 17 counties (powiats): 3 city counties, those being Białystok, Suwałki, and Łomża. It is also divided into 14 land counties, which these 14 counties are further divided into 118 gminas.

Metropolitan Białystok was designated by the Voivodeship in the Regulation No. 52/05 of 16 May 2005 in order to help economically develop the region. In 2006, the metropolitan area's population was 450,254 inhabitants. It covers an area of 1.521 km ². For one km, there are about 265 people. Among urban residents there are more women - 192 thousand. For every 100 men, there are 108 women on average. The municipalities adjacent to Białystok are slowly losing their agricultural character, becoming residential suburban neighborhoods.
