A by-election was held for the Craftian House of Representatives seat of Coastalis on Saturday 4 May 1991. It was triggered by the death of former Prime Minister and leader of the Protection of Craftia Party, Edwin Stevenson, on 14 April.
The by-election was won by Conservative candidate Martin Slaby on a swing of 53.26%, while the Protection Party, which held the seat before Stevenson's death, was virtually wiped out of the election, garnering only 3.42% of the popular vote after suffering a swing of 73.90% against it, the largest ever in a by-election.
