The number of unemployed in Europe's largest economy rose by 12,000 last month to 4.457 million people.
"Daddy must not lose his job"
Economists said this ninth consecutive rise would be followed by further increases in the months ahead.
"We have to expect a rise in January or February to above five million," said Dresdner bank economist Harald Joerg.
"No turnaround can yet be seen on the labour market", agreed Frank-Juergen Weise, head of the Federal Labour Agency.
The German economy has been growing by about 1.8% this year, but this has not been enough to spark a significant rise in job creation, economists said.
The country's unemployment figure remained unchanged last month at 10.7% after having been adjusted for seasonal factors.
The unadjusted figure, which offers less clear guidance of what is really going on, fell from 10.3% in September to 10.1% in October.
"The problem is that the global economy is already on a downwards path and momentum from exports will get weaker," said Helaba economist Stefan Muetze.
"A turnaround on the jobs market is slipping further into the distance."
And yet, the situation for Germany's jobless is not as bad as it seems, other economists pointed out.
"The rise in the jobless figure is also linked to the (welfare) reforms," said Mr Joerg.
"More people are registering in order not to lose their benefits."
Among the controversial reforms have been proposals to cut benefits for the long-term jobless, and to cut generous welfare plans as the population ages.
