A vote of no confidence, also variously called a motion of no confidence, no-confidence motion, motion of confidence, or vote of confidence, is a statement or vote about whether a person in a position of responsibility like in government or management is still deemed fit to hold that position, such as because they are inadequate in some aspect, fail to carry out their obligations, or make decisions that other members feel to be detrimental. The parliamentary motion demonstrates to the head of government that the elected parliament either has or no longer has confidence in one or more members of the appointed government. In some countries, a no-confidence motion being passed against an individual minister requires the minister to resign. In most cases, if the minister in question is the premier, all other ministers must also resign.

A censure motion is different from a no-confidence motion. Depending on the constitution of the body concerned, "no confidence" may lead to the dismissal of the council of ministers or other position-holders and often the dissolution of most of the leadership of the executive branch. On the other hand, "censure" is meant to show disapproval and does not result in the resignation of ministers. The motion of censure may be against an individual minister or a group of ministers. However, depending on a country's constitution, a no-confidence motion may be more directed against the entire cabinet. Again, depending on the applicable rules, censure motions may need to state the reasons for the motion, but specific reasons may not be required for no-confidence motions.
