The Lincoln Memorial Reflecting Pool is the largest of the many reflecting pools in Washington, D.C., U.S.. It is a long and large rectangular pool located on the National Mall, directly east of the Lincoln Memorial, with the Washington Monument to the east of the reflecting pool. Part of the iconic image of Washington, the reflecting pool hosts many of the 24 million visitors a year who visit the National Mall. It is lined by walking paths and shade trees on both sides. Depending on the viewer's vantage point, it dramatically reflects the Washington Monument, the Lincoln Memorial, the Mall's trees, and/or the expansive sky.

The Lincoln Memorial Reflecting Pool was designed by Henry Bacon, constructed in 1922 and 1923, following the dedication of the Lincoln Memorial.
