Primary legislation is legislation made by the legislative branch of government. This contrasts with secondary legislation, made by the executive branch, usually within boundaries laid down by the legislature.

In the UK, primary legislation is known as an Act of Parliament (In Wales, an Assembly Measure), and in the U.S., it is (at federal level) an Act of Congress. In European Union law, the founding treaties are the main primary legislation.
