An Act of Parliament is a statute (commonly called a law) enacted as primary legislation by a national or sub-national parliament. In the Republic of Ireland the term Act of the Oireachtas is used, and in the United States the term Act of Congress is used.

In Commonwealth countries, the term is used both in a narrow sense, as the formal description of a law passed in certain territories, and in a wider (generic) sense for primary legislation passed in any country.

A draft Act of Parliament is known as a bill.

In territories with a Westminster system, most bills that have any possibility of becoming law are introduced into parliament by the government. This will usually happen following the publication of a "white paper", setting out the issues and the way in which the proposed new law is intended to deal with them. A bill may also be introduced into parliament without formal government backing; this is known as a private member's bill.

In territories with a multicameral parliament, most bills may be first introduced in any chamber. However, certain types of legislation are required, either by constitutional convention or by law, to be introduced into a specific chamber. For example, bills imposing a tax, or involving public expenditure, are introduced into the House of Commons in the United Kingdom by convention, and in Canada's House of Commons and Ireland's Dáil as a matter of law. Conversely, bills proposed by the Law Commission and consolidation bills traditionally start in the House of Lords.

Parliament-Funkadelic is a funk, soul and rock music collective headed by George Clinton. Their style has been dubbed P-Funk. Collectively the group has existed under various names since the 1960s and has been known for top-notch musicianship, politically charged lyrics, outlandish concept albums and memorable live performances. They influenced numerous post-disco and post-punk music groups of the 1980s and 1990s.

The collective's origins date back to the doo-wop group The Parliaments, formed in the late 1950s in Plainfield, New Jersey. Under Clinton's direction, by the early 1970s the groups Parliament and Funkadelic were operating concurrently and consisted of the same stable of musicians playing different types of funk music for two different labels. The name "Parliament-Funkadelic" became the catch-all term for the multiple bands in Clinton's stable. By the late 1970s the collective had grown to include dozens of musicians recording and touring under many different group names and solo projects. (See P-Funk offshoot groups and solo ventures.) Overall, the collective achieved thirteen top ten hits in the American R&B music charts between 1967 and 1983, including six number one hits. Funkadelic is a funk band with a psychedelic rock touch whose influences include the amplifier sounds of Jimi Hendrix and Led Zeppelin, James Brown's funk, blues, Sun Ra's experimentation, Frank Zappa's and the Coasters' humour, the concept albums of the Beatles and the Who and southern soul artists like Otis Redding and Screamin' Jay Hawkins. Parliament is a funk/R&B band whose influences are the funky side of Hendrix and Sly Stone, Motown soul groups turned funk groups like the Temptations, the political songs of the Impressions, Rufus Thomas' southern funk, doo-wop groups like the Coasters for the humour and Frankie Lymon & the Teenagers.
