The Blauer Enzian is a named express train service that currently runs between Frankfurt in Germany and Klagenfurt in Austria. Introduced in 1951, it originally ran via the German North–South railway line between Hamburg and Munich. Labelled as an international Trans Europ Express (TEE) train, it also linked with Zell am See and Klagenfurt in Austria from 1969. Trains were operated by the Deutsche Bundesbahn (DB) and its Deutsche Bahn successor, from 1970 also by the Austrian Federal Railways (ÖBB).

The train's classification and formation (consist) varied over time. Since 1981, trains run from Dortmund to Klagenfurt, categorised as EuroCity service from 1987. It ceased to be a named train in 2002, but was revived in 2017 as an ÖBB EuroCity from Frankfurt to Klagenfurt, with through coaches onwards to Zagreb in Croatia.
