The 2009 IRB Junior World Rugby Trophy was the second IRB Junior World Rugby Trophy, the second-tier world rugby union championship for Under-20 national teams. The event is organised by rugby's governing body, the International Rugby Board (IRB). This competition, which is contested by eight men's junior national teams, was held in Nairobi, Kenya from April 21 to May 3.
The competition was won by Romania. Original plans called for them to receive an automatic berth into the following year's edition of the IRB Junior World Championship, the top tier of the IRB under-20 championship; however, Romania ultimately did not receive that berth after the Junior World Championship was reduced from 16 teams to 12.
