This is a list of former monarchs of sovereign states who are alive to date. While most monarchs retain their position for their lifetime, some choose to abdicate in favour of a younger heir, while other monarchs are deposed when their monarchies are abolished or when another ruler seizes power by force. By international courtesy, these individuals are usually still addressed by their monarchical titles. The most recent former monarch to die was King Constantine II of Greece, on 10 January 2023.
