The constructive vote of no confidence is a variation on the motion of no confidence that allows a parliament to withdraw confidence from a head of government only if there is a positive majority for a prospective successor. The principle is intended to ensure governments' stability by making sure that a replacement has enough parliamentary support to govern.

A motion or vote of no confidence is a formal expression by a deliberative body as to whether an officeholder is deemed fit to continue to occupy their office. The no-confidence vote is a defining feature of parliamentary democracy which allows the elected parliament to either affirm their support or force the ousting of the cabinet. Systems differ in whether such a motion may be directed against the prime minister only or against individual cabinet ministers.
