1872 California-Nevada State Boundary Marker, Political boundary marker in Washoe County and Sierra County, United States.

The 1872 California-Nevada State Boundary Marker is a cast iron obelisk placed on the state line between California and Nevada to mark the official division between the two territories. It stands within a small landscaped park area and is enclosed by a protective fence.

Alexey W. Von Schmidt ran the 1872 survey that fixed the line later upheld as the border. He placed stone, wood and iron markers along the route north to Oregon, and this cast iron pylon near Verdi marks the survey's initial point. Doubts persisted until a 1980 U.S. Supreme Court ruling adopted the Von Schmidt line between Oregon and Lake Tahoe.

The marker makes the border between California and Nevada tangible for anyone who visits. It shows how territorial lines were once made visible for settlers and travelers crossing this mountain landscape.

The marker is enclosed within a fenced area that allows for comfortable viewing up close. A visit during the drier months is a good idea, as the surrounding mountain region can be hard to reach in winter.

The marker's south face reads "1872, LONGITUDE 120 WEST OF GREENWICH, A.W. VON SCHMIDT, U.S." and the north face gives the distance to Oregon as 170 miles 47 chains, about 274.5 kilometres. The pylon was listed on the National Register of Historic Places in 1981 as the initial point of the survey.
