We present distances to 76 medium-sized molecular clouds and an extra large-scale molecular cloud in the second Galactic quadrant (104.75°<l<150.25° and |b|<5.25°), 73 of which are accurately measured for the first time. Molecular cloud samples are drawn from l-b-V space (-95<V_LSR<25km/s) with the density-based spatial clustering of applications with noise algorithm, and distances are measured with the background-eliminated extinction-parallax method using extinctions and Gaia DR2 parallaxes. The range of the measured distances to the 76 molecular clouds is from 211 to 2631pc, and the extra large-scale molecular cloud appears to be a coherent structure at about 1 kpc, across about 40° (∼700pc) in the Galactic longitude.
