The 1983 Australian Football Championships was an Australian football series between representative teams of the three major football states. Games involving Victoria were played under State of Origin rules, whilst the match between Western Australia and South Australia involved players based in their respective states at the time. The competition was won by Western Australia.

Representative matches in Australian rules football are matches between representative teams played under the Australian rules, most notably of the colonies and later Australian states and territories that have been held since 1879.For most of the 20th century, the absence of a national club competition in Australia and international matches meant that intercolonial and later interstate matches were regarded with great importance.
