The Lithuania men's national under-20 basketball team (Lithuanian: Lietuvos nacionalinė vaikinų jaunimo iki 20 krepšinio rinktinė), is the representative for Lithuania in international basketball competitions, and it is organized and run by the Lithuanian Basketball Federation.

[2][3] The Lithuania men's national under-20 basketball team represents Lithuania at the FIBA U20 EuroBasket.

The 2012 FIBA Europe Under-20 Championship champions generation (born 1992), led by Jonas Valančiūnas, won every single age-restricted tournament they have competed in.

No other generation in the world have shown such impressive performance.

Consequently, the unique Lithuanian generation was nicknamed "Auksinis Lietuvos jaunimas" (English: The Golden Lithuanian Youth).
