What is the nationality of tennis great Roger Federer? Swiss. Federer was born in Basel, Switzerland, and represented Switzerland throughout his tennis career.
He became one of the defining players of the modern game, winning 20 Grand Slam men’s singles titles. His record included eight Wimbledon championships, six Australian Opens, five US Opens, and one French Open. Federer’s elegant one-handed backhand, precise serving, and all-court style made him successful on grass, hard courts, and clay.
Federer also played for Switzerland in international team and Olympic competition. He helped Switzerland win its first Davis Cup title in 2014. At the 2008 Beijing Olympics, he won men’s doubles gold with Stan Wawrinka, another Swiss star. Federer later won singles silver at the 2012 London Olympics.
A small complication is that Federer also holds South African citizenship through his mother, Lynette, who was born in South Africa. That does not change the standard answer to this quiz question: in tennis, Federer is identified as Swiss and competed for Switzerland.
