Tennessee's 23rd Senate district is one of 33 districts in the Tennessee Senate. It has been represented by Republican Kerry Roberts since 2023. Prior to redistricting, Roberts had represented the 25th district which was located in the same spot as the current 23rd district.
District 23 is based in the rural and suburban areas to the west of Nashville, covering all of Cheatham, Dickson, Hickman, Humphreys, Robertson Counties, and part of Montgomery County. Communities in the district include Springfield, Dickson, Ashland City, Waverly, Greenbrier, Coopertown, Centerville, Pleasant View, White Bluff, and parts of White House, Portland, and Millersville.
The district is located entirely within Tennessee's 7th congressional district, and overlaps with the 66th, 68th, 69th, 74th, and the 78th districts of the Tennessee House of Representatives. It borders the state of Kentucky.
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.
