5806 Archieroy, provisional designation 1986 AG1, is a stony Hungaria asteroid from the inner regions of the asteroid belt, approximately 6 kilometers in diameter. It was discovered on 11 January 1986, by American astronomer Edward Bowell at Lowell's Anderson Mesa Station near Flagstaff, Arizona. It is named after Scottish astrophysicist Archie Roy.
The bright E-type asteroid, alternatively classified as a V-type, is a member of the Hungaria family, which form the innermost dense concentration of asteroids in the Solar System. It orbits the Sun at a distance of 1.9–2.0 AU once every 2 years and 9 months (1,005 days). Its orbit has an eccentricity of 0.04 and an inclination of 21° with respect to the ecliptic. A first precovery was taken at Palomar Observatory in 1954, extending the asteroid's observation arc by 32 years prior to its official discovery observation at Anderson Mesa.
Between 2004 and 2015, several rotational lightcurves of Archieroy have been obtained from photometric observations by American astronomers Brian Warner at his Palmer Divide Observatory, Colorado, and Robert Stephens at the Center for Solar System Studies, California. Lightcurve analysis gave a well-defined rotation period between 12.16 and 12.187 hours with a high brightness variation of 0.34 to 0.47 magnitude (U=3-/3/3/3).
