Abuse was scrawled on the outer wall of the Mauthausen camp near Linz overnight and no culprits had been found, Michael Tischlinger, head of the provincial anti-terrorism police, told the Austrian Press Agency.
"Such a desecration is not a prank, the culprits had a select target," said Willi Mernyi, head of the Mauthausen Committee which helps oversee the site where around 100,000 people died during Nazi rule in Austria in 1938-45.
"There is an active far-right scene in Upper Austria that does not even shrink away from vandalizing a former concentration camp," Mernyi said in a statement.
The case shows authorities need to clamp down more on the extreme right, local Social Democrat politician Josef Ackerl said. Local police and Austria's interior ministry were not available for comment.
Far-right parties together captured nearly a third of the vote in Austria's 2008 national elections and feed off xenophobia and anti-European sentiment in the insular Alpine Republic.
