The World Junior Teams Championship is a bridge competition for zonal teams of players up to about 25 years old.
Zonal signifies both organization by the World Bridge Federation (WBF) and qualification in eight WBF zones; for example (2006, 2008), six teams qualify from 'Europe' defined by European Bridge League membership. Zones may require national representation; for example, the six European teams must represent six member nations of the EBL.
The oldest event, sometimes called the Junior Teams without qualification, dates from 1987 with some changes in definition. Today that is the "open" u-26 tournament (Juniors) in contrast to the u-26 for women (Girls) and the open u-21 (Youngsters). It has been held every two years, odd-number years to 2005 and even years from 2006. Competitors vie for the Ortiz-Patiño Trophy, formerly presented by WBF President Emeritus Jaime Ortiz-Patiño (1930–2013) who conceived the idea while serving as WBF President in 1985. The even-year tournaments officially constitute the World Youth Teams Championships for so-called juniors, girls, and youngsters. The entries are national teams, representing countries affiliated with the WBF via membership in the eight geographical "zonal organizations". Moreover, they must qualify within their zones, usually by high standing in a zonal championship tournament that is limited to one team per member nation.
The 2008 junior teams championships were part of the inaugural World Mind Sports Games in Beijing, China. Denmark won its second gold medal, beating Poland in the final, while Norway won the bronze. The 1st Games also included under-28 and under-21 team championships won by Norway and France. Under-21 and u-26 are part of the WBF youth program (namely, two of the three World Youth Teams Championships) but u-28 is not.
In 2010 Israel defeated France in the Juniors final while China won the bronze medal. The event was part of the newly christened World Bridge Series that also included World Young Ladies Teams and under-21 World Youngsters Teams, both won by Poland.
In 2011, at the 2nd World Youth Congress, "Ned Juniors" comprising four players from the Netherlands won the main teams event, a six-day tournament with 27 entries. Ned Juniors won the full-day 56-deal final by 131 to 60 IMPs against "Arg Uru" from Argentina and Uruguay. Meanwhile, "Ned Rum", with one Dutch pair and one transnational pair from Romania and the United States, won third place against "France".
