We present multiepoch observations with the Very Long Baseline Array of SiO maser emission in the v ?=?1, J ?=?1?0 transition at 43 GHz from the remnant of the red nova V838 Mon. We modeled the positions of maser spots to derive a parallax of 0.166?±?0.060 mas. Combining this parallax with other distance information results in a distance of 5.6?±?0.5 kpc, which is in agreement with an independent geometric distance of 6.1?±?0.6 kpc from modeling polarimetry images of V838 Mon’s light echo. Combining these results, and including a weakly constraining Gaia parallax, yields a best estimate of distance of 5.9?±?0.4 kpc. The maser spots are located close to the peaks of continuum at ~225 GHz and SiO J ??=??5?4 thermal emission detected with the Atacama Large (sub)Millimeter Array. The proper motion of V838 Mon confirms its membership in a small open cluster in the Outer spiral arm of the Milky Way.
