At least 1.2 million Dutch nationals hold a second nationality but the number of people becoming Dutch citizens is falling, according to new figures from the national statistics office CBS.
In total, the number of dual nationals rose 40,000 during 2010, reaching 1.2 million by January 2011, the CBS said.
Almost half the dual nationals also hold Moroccan or Turkish nationality. Germans, British nationals and Belgians are next on the list of people entitled to more than one passport.
Half the increase is due to children being born to a mixed nationality family.
However, the number of people taking Dutch nationality fell to 18,000 in 2010, the lowest figure since the mid-1990s, the CBS said. Of them, 16,000 kept their original nationality as well.
The government said last week it plans to press ahead with controversial proposals to stop people keeping their original nationality if they become Dutch. Dutch nationals who take another nationality will also lose their Dutch passports.
