The German economy grew by 0.7% in 2012, a sharp slowdown on the previous year, preliminary figures show.
The figure was well below the 3% growth seen in 2011 and suggests the economy contracted in the fourth quarter.
"In 2012, the German economy proved to be resistant in a difficult economic environment and withstood the European recession," the federal statistics office Destatis said.
Some analysts believe the German economy will enter recession itself.
Destatis said economic activity "slowed down considerably" in the second half of the year, and particularly in the final quarter.
Last month, Germany's central bank, the Bundesbank, cut its growth forecast for this year to 0.4% and warned that the economy may have contracted in the final three months of 2012, and may do so again in first quarter of 2013.
The euro-zone economy as a whole is already in recession, having contracted in both in the third and fourth quarters of last year.
Spending boost
For 2012 as a whole, Destatis said foreign trade was "very robust", with exports up 4.1% on 2011. Imports grew by 2.3%. The positive trade balance was "once again the main driving force for economic growth in Germany".
Household expenditure increased by 0.8%, while government spending was up 1%.
The figures also showed that while the service sector of the economy expanded, industry and construction contracted.
Destatis will publish official fourth-quarter growth figures on February 14.
