A parliamentary group, parliamentary caucus or political group is a group consisting of members of different political parties or independent politicians with similar ideologies. Some parliamentary systems allow smaller political parties, who are not numerous enough to form parliamentary groups in their own names, to join with other parties or independent politicians in order to benefit from rights or privileges that are only accorded to formally recognized groups. An electoral alliance, where political parties associate only for elections, is similar to a parliamentary group. A technical group is similar to a parliamentary group but with members of differing ideologies. In contrast, a political faction is a subgroup within a political party and a coalition forms only after elections.
Parliamentary groups may elect a parliamentary leader; such leaders are often important political players. Parliamentary groups in some cases use party discipline to control the votes of their members.
