A minority government, minority cabinet, minority administration, or a minority parliament is a government and cabinet formed in a parliamentary system when a political party or coalition of parties does not have a majority of overall seats in the legislature. It is sworn into office, with or without the formal support of other parties, enabling a government to be formed. Under such a government, legislation can only be passed with the support or consent of enough other members of the legislature to provide a majority, encouraging multi-partisanship. In bicameral legislatures, the term relates to the situation in the chamber whose confidence is considered most crucial to the continuance in office of the government (generally, the lower house).
A minority government tends to be much less stable than a majority government because if they can unite for a purpose, opposing parliamentary members have the numbers to vote against legislation, or even bring down the government with a vote of no confidence.
To deal with situations in parliamentary systems where no clear majority to form a government exists, two or more parties may establish a formal coalition government, commanding a clear majority of the parliamentary members. A party might also enter into less formal alliances or agreements with other parties or individual members to allow the minority government to stay in office.
A common situation is a governance with "jumping majorities", where the cabinet stays as long as it can negotiate support from a majority in the parliament, even though that majority may be differently formed from issue to issue or bill to bill. On occasion, the legislature may permit a minority cabinet to continue in office despite having been defeated on a given vote, and a minority government might even bring on a confidence vote and threaten to resign should the legislature vote against it.
An alternative arrangement is a looser alliance of parties, exemplified by Sweden.
