The 2009–10 IRB Sevens World Series was the eleventh of an annual series of rugby union sevens tournaments for full national sides run by the International Rugby Board since 1999–2000. Samoa won the IRB Sevens World Series crown for their first time.

Sevens is traditionally played in a two-day tournament format. However, the most famous event, the Hong Kong Sevens, is played over three days, largely because it involves 24 teams instead of the normal 16.

The 2009-10 Series was won by Samoa, who won four of the eight tournaments and placed second in two others. Samoa were led by top try-scorer Mikaele Pesamino, who led the Series with 56 tries.
