The Little Rock, Rock formation in Arkansas, US.

The Little Rock is a reduced stone outcrop on the south bank of the Arkansas River in downtown Little Rock, beside the Junction Bridge, whose foundations enclose part of the rock. It was originally estimated to rise about 18 feet (5.5 m) above the river. The rock is jagged and upright, mottled gray, tan and ochre with rust-orange and dark streaks, and a rectangular bronze plaque is mounted on its right-facing side.

Jean-Baptiste Bénard de la Harpe, a French explorer, recorded the rock in 1722 as a landmark on the Arkansas River. In 1818 it served as a survey marker and became the starting point for land surveys south of the river. It was listed on the National Register of Historic Places in 1970.

The rock gave Little Rock its name: French explorer Jean-Baptiste Bénard de la Harpe noted it in 1722, and the "little rock" became the city's eponym. A bronze plaque is mounted on the stone today, and the Junction Bridge foundations enclose part of the outcrop.

The rock stands on a paved waterfront surface on the south bank of the Arkansas River, next to the Junction Bridge, whose foundations enclose part of the outcrop. The bronze plaque faces the walkway, so the stone can be examined on foot without entering the water.

The bronze plaque on the rock's right-facing side is not the only trace of the outcrop's role: in 1818 the rock served as a survey marker and became the starting point for land surveys south of the Arkansas River. Part of the outcrop also lies within the foundations of the adjacent Junction Bridge.
