We augmented our planetary search time series with lower cadence astrometric imaging and obtained two million images of approximately 1800 stars suspected to be mid-to-late M dwarfs. We fit an astrometric model to MEarth's images for 1507 stars and obtained trigonometric distance measurements to each star with an average precision of 5mas. Our measurements, combined with the Two Micron All Sky Survey photometry, allowed us to obtain an absolute K_s_ magnitude for each star. In turn, this allows us to better estimate the stellar parameters than those obtained with photometric estimates alone and to better prioritize the targets chosen to monitor at high cadence for planetary transits. The MEarth sample is mostly complete out to a distance of 25pc for stars of type M5.5V and earlier, and mostly complete for later type stars out to 20pc. We find eight stars that are within 10pc of the Sun for which there did not exist a published trigonometric parallax distance estimate. We release with this work a catalog of the trigonometric parallax measurements for 1507 mid-to-late M dwarfs, as well as new estimates of their masses and radii.2014ApJ...784..156Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/784/156CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/311 : Hipparcos, the New Reduction (van Leeuwen, 2007)I/298 : LSPM-North proper-motion catalog nearby stars (Lepine+, 2005)I/279 : Revised Luyten Half-Second Catalogue (Bakos+ 2002)I/239 : The Hipparcos and Tycho Catalogues (ESA 1997)I/238 : Yale Trigonometric Parallaxes, Fourth Edition (van Altena+ 1995)V/70 : Nearby Stars, Preliminary 3rd Version (Gliese+ 1991)I/98 : NLTT Catalogue (Luyten, 1979)I/87 : LHS Catalogue, 2nd Edition (Luyten 1979)J/ApJ/758/56 : Young M dwarfs within 25pc.
