Samoa at the 2008 Summer Olympics

Samoa sent a delegation to compete at the 2008 Summer Olympics in Beijing, China. The country was represented by a total of six athletes. The country's flagbearer during the Games' opening ceremony was weightlifter Ele Opeloge. Samoa won its first Olympic medal due to medals reallocation after the IOC's retesting of doping samples in 2016.
