The 1984 Sioux Falls mayoral election took place on April 24, 1984, following a primary election on April 10, 1984. Incumbent Mayor Rick Knobe declined to run for re-election to a third term.[1] Seven candidates ran to succeed him, producing a close primary election. Real estate agent Jack White and news anchor Joe Cooper placed first and second in the primary with 23 percent of the vote each, while insurance agent Don Kuck and businessman Neal Hines narrowly placed third and fourth with 22 percent each. In the general election, Cooper narrowly defeated White, 53-47 percent.
In 1985, voters ratified a change to the system of government, which cut Cooper's term from five years to two, forcing an early election in 1986.
