The 1985 Pacific Conference Games was the fifth and final edition of the international athletics competition between five Pacific coast nations: Australia, Canada, Japan, New Zealand and the United States. Like the 1981 edition before it, 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. One change was made to the event programme: the women's pentathlon was dropped in favour of the heptathlon, mirroring the same change in the Olympic programme which had happened at the 1984 Los Angeles Olympics.
