The Delaware State Senate is the upper house of the Delaware General Assembly, the state legislature of the U.S. state of Delaware. It is composed of 21 Senators, each of whom is elected to a four-year term, except when reapportionment occurs, at which time Senators may be elected to a two-year term. There is no limit to the number of terms that a Senator may serve. The Delaware Senate meets at the Legislative Hall in Dover.

In order to accommodate the ten-year cycle of reapportionment, the terms of office of the several Senators are staggered so that ten Senators are elected to terms of two years at the first biennial general election following reapportionment, followed by two four-year terms, and eleven Senators are elected at the said election for two four-year terms, followed by a two-year term.

Like other upper houses of state and territorial legislatures and the federal U.S. Senate, the Senate can confirm or reject gubernatorial appointments to the state cabinet, commissions, boards, or justices to the Delaware Supreme Court.
