Rinchnach is a municipality in the Lower Bavarian district of Regen, of Germany.

[citation needed] Rinchnach is in the midst of the Bavarian Forest, just 7 kilometers southeast of the town Rain, and 9 kilometers south of Zwiesel.

The village spreads over a wide, sunny valley at the foot of the Gsengetstein Mountain.

Saint Gunther, a Benedictine monk from the Niederaltaich Abbey, created the first settlement in the central Bavarian Forest when he founded the Rinchnach monastery in 1011.

[citation needed] The municipality was destroyed and looted in the Rinchnach Thirty Years' War in 1641.
