We present astrometric parallaxes for 18 suspected nearby stars selected fromthe LSPM-north proper motion catalog. Sixteen objects are confirmed to be mainsequence M dwarfs within 16 parsecs of the Sun, including three stars (LSPMJ0011+5908, LSPM J0330+5413, LSPM J0510+2714) which lie just within the 10parsec horizon. Two other targets (LSPM J1817+1328, LSPM J2325+1403) areconfirmed to be nearby white dwarfs at distances of 14 and 22 parsecs,respectively. One of our targets, the common proper motion pair LSPMJ0405+7116E + LSPM J0405+7116W, is revealed to be a triple system, with thewestern component resolved into a pair of 16th magnitude stars (LSPMJ0405+7116W-A and LSPM J0405+7116W-B) with a 0.7"+/-0.1" angular separation. Wefind two stars (LSPM J1314+1320 and LSPM J1757+7042) to be significantlyoverluminous for their colors, and suggest that these may be unresolveddoubles/multiples.
