Nico Rosberg (born 27 June 1985 in Wiesbaden, West Germany) is a racing driver for the Mercedes GP Formula One team. He races under the German flag  in Formula One, although he competed for Finland earlier in his career. He holds dual nationality of these two countries.

Rosberg won the 2005 GP2 Series for the ART team, having raced in Formula Three Euroseries previously for his father's team.

Rosberg joined the re-branded Mercedes team, formed by the takeover of 2009 constructors' champions Brawn GP, for the 2010 Formula One season.

The son of Finnish 1982 Formula One World Champion Keke Rosberg and his wife Sina, Nico spent much of his youth in Monaco with his family, and still lives in the principality. Rosberg speaks fluent German, English, Italian, Spanish and French; but only a little Finnish, though he is learning the language.

In lower formulae drivers race under the nationality of the country that issued their racing licence. Rosberg competed under the Finnish and German flags at different times during his early career.

In Formula One, as for all FIA world championships, a driver's nationality is defined by his passport. Rosberg races under the German flag in Formula One as of 2009. He is friends with fellow Formula 1 drivers Lewis Hamilton and Adrian Sutil.
