Parliamentary democracy is a system of government in which the executive branch derives its legitimacy and authority from the legislature and remains accountable to it. In such systems, the head of government, commonly titled prime minister, is usually a member of the parliament and is chosen by the legislature from among its members. The cabinet is responsible to the parliament and can be dismissed by a vote of confidence.

Most parliamentary democracies feature a separation between head of state and head of government; the head of state is often a ceremonial president or constitutional monarch. Legislation is typically proposed by the government, debated in parliament, and requires the confidence of the majority to pass. Governments tend to stay in office as long as they retain the support of the majority, leading to votes of no confidence as a mechanism to change government without elections.

Variants include the Westminster model with strong party discipline and first-past-the-post elections, as seen in the United Kingdom, Canada, and Australia; and many continental European systems that use proportional representation and coalition governments, such as Germany and Sweden. In some systems, the same party or coalition that holds a majority forms the government, while in others coalitions require negotiation and compromise.

Advantages of parliamentary democracy include direct accountability to parliament, clearer responsibility, and potential for flexible government formation. Criticisms include reliance on party discipline, potential for legislative gridlock in multiparty coalitions, and the possibility that the head of state has little real political influence. Parliamentary democracy is often contrasted with presidential or semi-presidential systems.
