The Meades Ranch Triangulation Station is a survey marker in Osborne County in the state of Kansas in the Midwestern United States. The marker was initially placed in 1891; from 1901 to 1989, it was the reference location relative to which all locations on the United States were measured, and from 1913 to 1989, it was the reference location for all surveys in the continent.
