The Senate is the upper house of the French Parliament, with the lower house being the National Assembly, the two houses constituting the legislature of France. The French Senate is made up of 348 senators elected by part of the country's local councillors, as well as by representatives of French citizens living abroad. Senators have six-year terms, with half of the seats up for election every three years.

An upper house is one of two chambers of a bicameral legislature, the other chamber being the lower house. The house formally designated as the upper house is usually smaller and often has more restricted power than the lower house. A legislature composed of only one house is described as unicameral.
