A premier is an executive official of government.

In many nations, the title "premier" is used interchangeably with "prime minister": for example, the "Italian Premier" is the same person as the "Italian Prime Minister". In the People's Republic of China, "premier" is more common, but "prime minister" is still used (see Premier of the People's Republic of China).

In Bermuda, a British overseas territory, the elected head of government is called the "premier". In other overseas territories, elected heads are called the chief minister. In the Cayman Islands, this position is known as the Leader of Government Business.
