Rottenmann (; Central Bavarian: Rottnmau) is a town in Styria in Austria, near the Rottenmanner Tauern. Rottenmann was first referred to in a document in 927. It received its town charter in 1279 from King Rudolf von Habsburg.
The name Rottenmann is a semi-translation of old Slavic *ÃÂÃÂrmÃÂnâ²ane, ultimately derived from the adjective *ÃÂÃÂrmÃÂnà'red' (cf. German rot 'red'). The place name was recorded in 1048 as Cirminah, derived from the hydronym *ÃÂÃÂrmÃÂna 'red (river)'.
