Tennessee's 33rd Senate district is one of 33 districts in the Tennessee Senate.

It has been represented by Democrat London Lamar since 2022, following her appointment by the Shelby County Commission after Katrina Robinson was expelled by the Senate.

By most measures, it is the most Democratic-leaning district in the state.

District 33 is based in South and Southwest Memphis, also covering small parts of Germantown, Collierville, and other Shelby County suburbs.

It overlaps with the 83rd, 84th, 85th, 87th, 91st, and 93rd districts of the Tennessee House of Representatives,[3] and borders the state of Mississippi.
