The Tanzania national rugby union team represents Tanzania in international rugby union. They are known as the Twigas (Swahili for "giraffes"). Tanzania are a member of the International Rugby Board (IRB), and have yet to play in a Rugby World Cup tournament. In the 1970s expatriates and Tanzanians regularly played in the national team in an annual competition against Kenya. Tanzania played their first officially recognised international in 2004, defeating Burundi. Tanzania won the CAR Castel Cup in 2006.
Tanzania won the 2007 CAR Castel Cup Division 2, South Zone, Pool A tournament held in Arusha late June. The 'Twigas' defeated Mayotte 18-11 on June 26 and Rwanda 53-6 on June 30. Burundi were unable to send their team. Tanzania went on to play Botswana, the winner of South Zone, Pool B, in Gaborone on 18 August. Tanzania lost 14-37
