Father of the House is a title that has been traditionally bestowed, unofficially, on certain members of some legislatures, most notably the House of Commons in the United Kingdom. In some legislatures the title refers to the longest continuously serving member, while in others it refers to the oldest member. Recently, the title Mother of the House or Mother of Parliament has also been used, although the usage varies among countries; it is either the female alternative to Father of the House, being applied when the relevant member is a woman, or refers to the oldest or longest-serving woman without reference to male members.
