Goleniów [ɡɔˈlɛɲuf] (Kashubian: Gòłonóg; German: Gollnow) is a town in Pomerania, northwestern Poland with 22,844 inhabitants as of 2011. It is the capital of Goleniów County in West Pomeranian Voivodeship. The town's area is 12.5 square kilometres (4.8 sq mi), and its geographical position is 53°33'N, 14°49'E. It is situated in the centre of Goleniowska Forest on Goleniów Plain, near main roads numbers 3 and 6.

The international airport Szczecin-Goleniów "Solidarność" Airport is located just east of the town.

The settlement dates back to the 10th century. Pomerania became part of the emerging Polish state under its first ruler Mieszko I around 967. As a result of the 12th-century fragmentation of Poland it became part of the separate Duchy of Pomerania, ruled by the House of Griffin. Barnim I, Duke of Pomerania granted the settlement Magdeburg town rights and additional privileges in 1264, yet Goleniów was rechartered with Lübeck Law, which favoured the local merchants, in 1314. The town grew by exploiting the vast timber reserves in the town-owned forests, and by trade. The town was connected to the Baltic Sea trade routes by the port of Ihnamünde (Inoujście) at the mouth of the Ina river. Competition with nearby Stettin (Szczecin) led to a series of conflicts between the two towns, the differences were set aside only in 1615 when the towns signed a reconciling treaty. The town remained part of the Duchy of Pomerania until Sweden took over in 1630.

The Thirty Years' War devastated the town, and as a consequence of the post-war Peace of Westphalia (1648) and Treaty of Stettin (1653), the town remained with Sweden who had occupied the area since the Treaty of Stettin (1630). The border with Brandenburg-Prussian Pomerania now ran close to the town, and cut Gollnow off from its economic hinterland, which hindered recovery from the war. Between 1677 and 1683, Gollnow was occupied by Brandenburg-Prussia. In the years that followed, the number of craftsmen in the town grew steadily. In 1720, Sweden lost its possessions south of the Peene and east of the Peenestrom rivers, including Gollnow, to Prussia in the Treaty of Stockholm. In the 19th century, craft and trade were joined by industry – Gollnow hosted a coppersmith, a needle fabrication, several facilities for the manufacturing of furniture, three breweries, a distillery, and five water mills. In the late 19th and early 20th century, the town became an important railroad junction, when it was connected to Neudamm (Dębno) and Naugard (Nowogard) in 1882, to Cammin (Kamień Pomorski) and Wollin (Wolin) in 1892, and to Massow in 1903. Gollnow was part of the Prussian province of Pomerania from 1815 to 1945. With the unification of Germany in 1871, it became part of the German Reich. In 1919, the Germans operated a camp in the town, in which they imprisoned Poles arrested in Szubin during the Greater Poland uprising.

During World War II, the Nazis operated a prison in the town, with multiple forced labour subcamps located in the region. Polish forced labourers were imprisoned in the town. On 7 March 1945, the town was captured by the Red Army. After Nazi Germany's defeat in World War II, the area became once again part of Poland, although with a Soviet-installed communist regime, which stayed in power until the Fall of Communism in the 1980s. The town's German population was expelled in accordance with the Potsdam Agreement.

In 1954, town limits were expanded by including Helenów as Goleniów's new district. From 1975 to 1998, it was administratively located in the Szczecin Voivodeship.
