The 1890 South Australian Football Association season was the 14th season of the top-level Australian rules football competition in South Australia.
Despite protests from Gawler the 1890 Programme gave them only five home games (one each against the other clubs) and two away games in Adelaide against each of the city clubs. They forfeited both of their games against Port Adelaide at Alberton and ended up collecting the wooden spoon. The end of year report stated they had a good deal to put up with in the way of a badly arranged programme, for they were brought down to town Saturday after Saturday, and sometimes to play the same team on two successive Saturdays. Despite rumours during the season that they were going resign they voted to complete their scheduled games.
The Gawler Football Association subsequently withdrew their Senior Club from the SAFA before the beginning of 1891 season and continued its own competition with 3 local teams, the predecessor of the current Barossa Light and Gawler Football Association.
