Łyna may refer to:
The Łyna (Polish pronunciation: [ˈwɨna]; German: Alle ; Lithuanian: Alna), or Lava (Russian: Лава), is a river in northern Poland's Warmian-Masurian Voivodeship as well as in Russia's Kaliningrad Oblast.
The Łyna is a tributary of the Pregolya River, and has a total length of 264 km (190 km in Poland - making it the 11th longest river there - and 74 km in Russia) and a basin area of 7,126 km² (5,719 km² in Poland). It is connected to Lake Mamry by the 18th-century Masurian Canal.
In historical terms, the river fell within the area of the medieval Monastic state of the Teutonic Knights established in the 13th century. The adjacent territory became later known as East Prussia, and then an easternmost province of Germany until 1945 when, in accordance with border changes promulgated at the Potsdam Conference, it was split between Poland and the Soviet Union.
Cities and towns founded by the Teutonic Knights along the river Łyna (Alnā) include:

Łyna [ˈwɨna] (German: Lahna, Lithuanian: Alna) is a village in the Warmian-Masurian Voivodeship in Poland, 16 km north of Nidzica in Nidzica County. It has a population of 440. It lies approximately 9 kilometres (6 mi) north of Nidzica and 40 km (25 mi) south of the regional capital Olsztyn.
The village is situated near the source of the River Alle, which is also named Łyna in Polish.
The village shares most of its history with that of Nidzica and Nidzica County.
It was first mentioned on 12 March 1387. At least since 1540 until 1945, Lahna was the seat of an evangelical Kirchspiel (church parrish) that included the towns of Allendorf, Commusin, Dietrichsdorf, Gutfeld, Glinken, Jablonken, Lykusen, Orlau, Radomin, Terten, Wolfsgarten, Wolka.
The Battle of Tannenberg (1914) of August 1914 took place nearby.
In 1945, while many if not most German civilians had fled the area, many of those who remained experienced atrocities at the hands of Soviet soldiers who found themselves on German soil for the first time. Lev Kopelev, a Soviet officer and later dissident, described how he was appalled by the acts of murder and looting against those who remained. After World War II the local populace was expelled to West Germany and the town and district became part of Poland as Powiat nidzicki. The area has been henceforth known by its present official name, Łyna.
