739 Mandeville, formerly referred to as 1913 QR and 1963 HE, is a minor planet located in the asteroid belt. Its absolute magnitude is 8.50. It was discovered on 7 February 1913 by Joel Hastings Metcalf in Winchester, Massachusetts.[3]

The orbital characteristics are calculated from the epoch of 4 January 2010, at which time 739 Mandeville had an orbital period of 1656 days and an orbital axis of 2.74 AU with eccentricity 0.14. Thus, its minimum distance from the sun was 2.35 and its maximum was 3.13. Its orbital inclination was found to be 20.71°, and its mean anomaly 116.58°.
