The French economy grew by 1.1% in 2015, according to the country's official statistics agency, its fastest growth for four years.
Official figures showed the economy grew 0.2 percentage points faster than in 2014. But it slowed to 0.2% in the final quarter of the year, compared with 0.3% in the third quarter.
The highest growth in four years comes despite two significant terrorist attacks in Paris last year. In January, gunmen stormed the offices of Charlie Hebdo, killing 12 people. And 130 people were killed in attacks across the city in November.
Finance Minister Michel Sapin said the French people "did not give up", and described 2015 as "the year of recovery". Mr Sapin said he expects that recovery to intensify in 2016.
Despite positive news on economic growth, the number of people in unemployment rose to a new record of 3.59 million.
