The Serbian men's national tennis team represents Serbia in the Davis Cup and the ATP Cup, both tennis competitions. Since June 2006, the team has played under the name of Serbia, following the split of Serbia and Montenegro.

The Davis Cup is the premier international team event in men's tennis. It is run by the International Tennis Federation (ITF) and is contested annually between teams from over 150 competiting countries, making it the world's largest annual team sporting competition. It is described by the organisers as the "World Cup of Tennis", and the winners are referred to as the World Champions. The competition began in 1900 as a challenge between Great Britain and the United States. By 2023, 155 nations entered teams into the competition.
