Vänern (/ˈveɪnərn/ VAY-nərn, US also /ˈvɛnərn/ VEN-ərn, Swedish: [ˈvɛ̂ːnɛɳ]) is the largest lake in Sweden, the largest lake in the European Union and the third-largest lake in Europe after Ladoga and Onega in Russia. It is located in the provinces of Västergötland, Dalsland, and Värmland in the southwest of the country. With its surface located at 44 metres (144 ft) above sea level and a maximum depth of 106 metres (348 ft), the lowest point of the Vänern basin is 62 metres (203 ft) below sea level. The average depth is a more modest 27 metres (89 ft), which means that the lake floor is above sea level on average.

Vänern drains into Göta älv towards Gothenburg and the Kattegat opening strait between the Atlantic Ocean’s North Sea and the Baltic Sea. It is the only one of the ten largest lakes in Sweden not to drain out to the eastern coastline. The Göta Canal built in the 19th century forms a waterway that runs to Vättern wholly rising when proceeding eastward, and then a navigable river linking the east coast with Vänern. The main inflow of water comes from Klarälven entering Vänern near Karlstad with its source in Trøndelag in Norway.

Carl Adolph Agardh (23 January 1785 in Båstad, Sweden – 28 January 1859 in Karlstad) was a Swedish botanist specializing in algae, who was eventually appointed bishop of Karlstad.
