The Netherlands competed at the 1984 Summer Olympics in Los Angeles, United States. 136 competitors, 82 men and 54 women, took part in 74 events in 15 sports.^[1]

Both of the Dutch archers from the 1980 competition returned in 1984. Both shot much higher scores than they had four years earlier, but the field was more competitive with the return of many nations that had boycotted, and both dropped out of the top eight.
