We use 612 single stars with previously published trigonometric parallaxesplacing them within 25 pc to evaluate parallaxes released in Gaia's first datarelease (DR1). We find that the Gaia parallaxes are, on average, $0.24 \pm0.02$ mas smaller than the weighted mean trigonometric parallax values forthese stars in the solar neighborhood. We also find that the offset changeswith distance out to 100 pc, in the sense that the closer the star, the largerthe offset. We find no systematic trends in the parallax offsets with stellar$V$ magnitude, $V-K$ color, or proper motion. We do find that the offset isroughly twice as large for stars south of the ecliptic compared to those thatare north.
