The 1981 Pacific Conference Games was the fourth edition of the international athletics competition between five Pacific coast nations: Australia, Canada, Japan, New Zealand and the United States. This was the first occasion that athletes from beyond the Pacific grouping were allowed to compete at the tournament. A total of 21 men's and 16 women's athletics events were contested. Combined track and field events were included for the first time, in the form of the men's decathlon and the women's pentathlon. The women's 3000 metres was also a new addition to the programme.
