The Maine Senate is the upper house of the Maine Legislature, the state legislature of the U.S. state of Maine. The Senate currently consists of 35 members representing an equal number of districts across the state, though the Maine Constitution allows for "an odd number of Senators, not less than 31 nor more than 35".[1] Unlike the lower House, the Senate does not set aside nonvoting seats for Native tribes. Because it is a part-time position, members of the Maine Senate usually have outside employment as well.
The Senate meets at the Maine State House in Augusta. Members are limited to four consecutive terms with each term being two years but may run again after a two-year wait.
Unlike many U.S. states, the Senate's leader is not the lieutenant governor, as Maine does not have a lieutenant governor. Instead, the Senate chooses its own president, who is also the first in the line of gubernatorial succession.

現在、選挙区は北から南へ1から番号が振られています。10年ごとの選挙区再編成ではこの番号順が逆転することが多いのですが、2021年に行われ、2022年の予備選挙と本選挙から施行された選挙区再編成では逆転されませんでした。2013年に策定され、2014年の予備選挙と本選挙で初めて使用された以前の選挙区境界線は、メイン州が他のほとんどの州に合わせて議会選挙区再編成のサイクルを調整したため、通常の10年ではなく8年間しか有効ではありませんでした。
