Wiżajny ([viˈʐai̯nɨ]; Lithuanian: Vižainis) is a village in Suwałki County, Podlaskie Voivodeship, in north-eastern Poland, close to the border with Lithuania.

The first mention of the settlement comes from 1253 when it was recorded as "Weyze", which was most likely taken from the name of a nearby lake, which in turn was derived from the Lithuanian word vėžys, or crawfish.

According to legend, in 1409 Grand Duke of Lithuania and King of Poland Władysław Jagiełło hunted aurochs here and hence called the place Stumbrinė.

[5] He was arrested again in April 1940 in Mikaszówka and deported to the Soldau and Sachsenhausen concentration camps, where he died of exhaustion in June 1940 (see Nazi crimes against the Polish nation).

[6] In 1947–1961, the local parish priest was Kazimierz Równy, former prisoner of the Soldau, Sachsenhausen and Dachau concentration camps.
