We present Atacama Large Millimeter/submillimeter Array (ALMA) Cycle 3observations of CO(2-1) emission from the circumnuclear disk in the E/S0 galaxyNGC 1332 at 0.044" resolution. The disk exhibits regular rotational kinematicsand central high-velocity emission (+/-500 km/s) consistent with the presenceof a compact central mass. We construct models for a thin, dynamically colddisk in the gravitational potential of the host galaxy and black hole, and fitthe beam-smeared model line profiles directly to the ALMA data cube. Model fitssuccessfully reproduce the disk kinematics out to r=200 pc. Fitting models justto spatial pixels within projected r=50 pc of the nucleus (two times largerthan the black hole's gravitational radius of influence), we findM_BH=6.64(-0.63,+0.65)*10^8 solar masses. This observation demonstrates ALMA'spowerful capability to determine the masses of supermassive black holes byresolving gas kinematics on small angular scales in galaxy nuclei.
