This is a list of highest points in the U.S. state of Arizona, in alphabetical order by county. Elevations are from USGS 1:24,000 scale topographic quadrangle maps. Elevations followed by a plus sign (+) are minimal values. The contour interval is shown after the (+).
Robert Walko listed the Arizona county high points and then hiked them in 1977.[1] At that time there were only 14 counties in the state, as La Paz county was not split from Yuma county until 1983.
