The Moldovan National Teams are from the Eastern European country of Moldova.
The Moldovan team was beaten in the final of the 2010 Quidditch World Cup by a team from China, in an exciting match that lasted for three days (Pm).
An outbreak of Dragon Pox during training meant they did not qualify for the 2014 tournament (Pm).
Although Moldova was in the Quidditch World Cup, there are not any Quidditch or other wizarding sports listed on its Wikipedia entry (Wikipedia).
