The Rennert Mound Archeological District is a group of archaeological sites in the southwestern part of the U.S. state of Ohio.

Located west of Elizabethtown in Hamilton County,[2] the site is composed of one Native American mound and the remnants of two others,[3] spread out over an area of 40 acres (16 ha).

Because the mound has never been excavated professionally, no significant artifacts have been recovered from it; consequently, the culture of the builders is unknown.

[4]: 120 Three mounds once composed the Rennert complex, but neither of the others can be distinguished from the surrounding landscape; however, it is believed that an archaeological investigation might be able to discover their locations.

[3] Yet other sites have been found in the vicinity: a somewhat smaller mound tops a hill to the north,[4]: 120  and the Wesley Butler Archeological District, composed of multiple mounds and a village site, lies just to the southwest.
