We present 114 trigonometric parallaxes for 107 nearby white dwarf (WD)systems from both the Cerro Tololo Inter-American Observatory ParallaxInvestigation (CTIOPI) and the U. S. Naval Observatory Flagstaff Station (NOFS)parallax programs. Of these, 76 parallaxes for 69 systems were measured by theCTIOPI program and 38 parallaxes for as many systems were measured by the NOFSprogram. A total of 50 systems are confirmed to be within the 25 pc horizon ofinterest. Coupled with a spectroscopic confirmation of a common proper motioncompanion to a Hipparcos star within 25 pc as well as confirmation parallaxdeterminations for two WD systems included in the recently released Tycho GaiaAstrometric Solution (TGAS) catalog, we add 53 new systems to the 25 pc WDsample $-$ a 42% increase. Our sample presented here includes four strongcandidate halo systems, a new metal-rich DAZ WD, a confirmation of a recentlydiscovered nearby short-period (P = 2.85 hr) double degenerate, a WD with a newastrometric pertubation (long period, unconstrained with our data), and a newtriple system where the WD companion main-sequence star has an astrometricperturbation (P $\sim$ 1.6 yr).
