We have identified 85 regions of enhanced Halpha emission at \b\ > 10degrees subtending approximately 1degrees or less on the Wisconsin Ha Mapper (WHAM) sky survey. These high-latitude WHAM point sources have Halpha fluxes of 10(-11) -10(-9) ergs cm(-2) s(-1), radial velocities within about 70 km s(-1) of the LSR, and line widths that range from less than 20 to about 80 km s(-1) (FWHM). Twenty-nine of these enhancements are not identified with either cataloged nebulae or hot stars and appear to have kinematic properties that differ from those observed for planetary nebulae. Another 14 enhancements are near hot evolved low-mass stars that had no previously reported detections of associated nebulosity. The remainder of the enhancements are cataloged planetary nebulae and small, high-latitude H II regions surrounding massive O and early B stars.
