Upper house
From Ballotpedia
The term upper house refers to one of two state legislative chambers in a bicameral legislature. An upper house, or state senate, is the upper deliberative body, or chamber, in states with a bicameral legislature. A state senate normally has fewer members — usually one-half to one-third as many members — as a state assembly or state house of representatives.
