Tennessee's 25th Senate district is one of 33 districts in the Tennessee Senate. It has been represented by Republican Ed Jackson since 2023. Prior to redistricting, he represented the 27th district which was at the time located in the same general area as the current 25th district.
District 25 spans the state's border along the Mississippi River, also stretching inland to cover the city of Jackson. The district covers all of Crockett, Dyer, Lake, Madison, Henderson, Decatur, and Perry Counties; other communities within the district include Dyersburg, Tiptonville, Newbern, and Alamo.
The district is located entirely within Tennessee's 8th congressional district. It borders the states of Kentucky, Missouri, and Arkansas.
Tennessee Senators are elected to staggered four-year terms, with odd-numbered districts holding elections in midterm years and even-numbered districts holding elections in presidential years.
