We directly construct model-independent mass profiles of galaxy clusters fromcombined weak-lensing distortion and magnification measurements within aBayesian statistical framework,which allows for a full parameter-spaceextraction of the underlying signal. This method applies to the full range ofradius outside the Einstein radius, and recovers the absolute massnormalization. We apply our method to deep Subaru imaging of five high-mass(>10^{15}M_{sun}) clusters, A1689, A1703, A370, Cl0024+17, and RXJ1347-11, toobtain accurate profiles to beyond the virial radius (r_{vir}). For eachcluster the lens distortion and magnification data are shown to be consistentwith each other, and the total signal-to-noise ratio of the combinedmeasurements ranges from 13 to 24 per cluster. We form a model-independent massprofile from stacking the clusters, which is detected at 37{\sigma} out to R ~1.7r_{vir}. The projected logarithmic slope steepens from -1.01 \pm 0.09 at R ~0.1r_{vir} to -1.92 \pm 0.51 at R ~ 0.9r_{vir}. We also derive for each clusterinner strong-lensing based mass profiles from deep HST/ACS observations, whichwe show overlap well with the outer Subaru-based profiles and together are welldescribed by a generalized form of the Navarro-Frenk-White profile, except forthe ongoing merger RXJ1347-11, with modest variations in the central cusp slope(-dln{\rho}/dlnr < 0.9). The improvement here from adding the magnificationmeasurements is significant, ~30% in terms of cluster mass profilemeasurements, compared with the lensing distortion signal.
