<p> We have compiled the first all-sky mid-infrared variable-star catalog based on Wide-field<br>
Infrared Survey Explorer (WISE) five-year survey data. Requiring more than 100 detections<br>
for a given object, 50,282 carefully and robustly selected periodic variables are discovered,<br>
of which 34,769 (69%) are new. Most are located in the Galactic plane and near the equatorial<br>
poles. A method to classify variables based on their mid-infrared light curves is established<br>
using known variable types in the General Catalog of Variable Stars. Careful classification of<br>
the new variables results in a tally of 21,427 new EW-type eclipsing binaries, 5654 EA-type <br>
eclipsing binaries, 1312 Cepheids, and 1231 RR Lyraes. By comparison with known variables <br>
available in the literature, we estimate that the misclassi- fication rate is 5% and 10% for<br>
short- and long-period variables, respectively. A detailed comparison of the types, periods, <br>
and amplitudes with variables in the Catalina catalog shows that the independently obtained <br>
classifications parameters are in excellent agreement. This enlarged sample of variable <br>
stars will not only be helpful to study Galactic structure and extinction properties, <br>
they can also be used to constrain stellar evolution theory and as potential candidates for<br>
the James Webb Space Telescope.<br>
