A Member of Parliament is a representative of the voters to a parliament. In many countries with bicameral parliaments, the term applies specifically to members of the lower house, as upper houses often have a different title, such as senate, and thus also have different titles for its members, such as "senators".

Members of parliament tend to form parliamentary groups (also called parliamentary parties) with members of the same political party. In everyday use, the term Member of Parliament is almost always shortened to the initialism "MP", and this is also common in the media.

In Australia, the term "MP" refers to a Member of the House of Representatives, the lower house of the Commonwealth (i.e. federal) parliament. Members may use "MP" after their names; "MHR" is not used, although it was used as a post-nominal in the past. A member of the upper house of the Commonwealth parliament, the Senate, is known as a "Senator".

In the Australian states of New South Wales and Victoria, a Member of the Legislative Assembly (lower house) may also use the post-nominal "MP". Members of the Legislative Council (upper house) use the post-nominal "MLC".
