The South Dakota Legislative Conflict of Interest Amendment, also known as Amendment C, was on the November 3, 1998 ballot in South Dakota as a legislatively-referred constitutional amendment, where it was defeated. The measure would have allowed state legislators to be elected or appointed into a state or local office if the office was created or the compensation was increased by the legislature during the legislator's term. The measure also would have allowed state legislators to hold state executive or administrative offices during their term if they were not compensated.
