Charles Edward Karst, known as Ed Karst (September 18, 1931 – July 17, 1992), was an attorney and politician remembered for his controversial tenure as the mayor (1969–1973) of Alexandria, the seat of Rapides parish and the largest city in central Louisiana. In 1991, Karst launched a bizarre "No Party" gubernatorial campaign in which he threatened if elected to fire the members of the Louisiana Supreme Court or, if defeated, as he was, to kill the justices, who had upheld his disbarment.
