The Robert Simpson Woodward House is a former residence located at 1513 16th Street, NW in the Dupont Circle neighborhood of Washington, D.C. From 1904 until 1914, it was a home of geologist Robert Simpson Woodward (1849–1924), the first president of the Carnegie Institution and a highly regarded scientist and science administrator.

It is a four-story brick building with Romanesque styling, and is not of particular architectural significance.

Prominent features include hipped dormers with tile roofing, the entrance recessed under a rounded arch, and the right-side curved window bay that extends to the third floor.

In a long and distinguished career, Woodward made substantive contributions to the fields of astronomy, mathematics, surveying, and geology.

He was also known as an effective administrator, serving as dean of the Columbia University School of Pure Science before becoming the first head of the Carnegie Institution in 1903.
