The Serbia and Montenegro men's national water polo team, also widely known as the FR Yugoslavia men's national water polo team, represented Serbia and Montenegro in international water polo games, from 1993 to 2006. It was governed by the Water Polo Association of FR Yugoslavia (1992–2003), then the Water Polo Association of Serbia and Montenegro (2003–2006). The team won medals in the Olympics, World and European Championships, FINA World Cup, FINA World League, Mediterranean Games and Universiade.
That national team was originally named either "Yugoslavia men's national water polo team", or "FR Yugoslavia men's national water polo team", from 1992 until 2003, after the country's name at the time. In 2003, after the country was renamed from FR Yugoslavia to Serbia and Montenegro, the team was also renamed to "Serbia and Montenegro men's national water polo team". After Serbia and Montenegro split up, in 2006, and became the independent countries of Serbia and Montenegro, they each formed their own successor national teams. The first appearance of the Serbia men's national water polo team at a major international competition was at the 2006 European Championship. While the first appearance of the Montenegro men's national water polo team at a major international competition was at the 2007 FINA World League.
