The 2008 USA Sevens competition took place on February 9 and 10 at Petco Park in San Diego, California.

It was the fourth Cup trophy in the 2007-08 IRB Sevens World Series.

The top-level Cup competition was won by New Zealand, who became the first team in the history of the IRB Sevens to win the first four tournaments of a season; it was also the Kiwis' sixth consecutive tournament win overall.

In the Cup semifinal against Kenya, they made history with their 35th consecutive match win in the IRB Sevens, breaking their own record set in 2001/02.
