You can request that Staff enable uploading font files (.ttf, .otf, .woff, .eot) to your wiki by sending a message using Special:Contact/general. Once they do this, you can upload fonts to your wiki using Special:Upload as with any other file, like an image&mdash;it's strongly recommended that you use a font licensed under a free license or one you have permission for from the copyright holder. After uploading the font, go to its file description page (File:FontName.thefont'sformat), and right-click the icon there to copy its URL.

With the font uploaded, place the following at the top of MediaWiki:Common.css to make it available to CSS: @font-face { font-family: 'FontName'; font-weight: normal; /* this can be 'bold', 'normal', 'semibold', 'light', depending on the file */ font-style: normal; /* this can be 'italic', 'normal', 'small-caps', depending on the file */ src: url(your/font/url/from/above) format( 'yourformat' ), url(another/format/of/your/font) format( 'otherformat' ); } Then this font can be used in CSS like any other. Additionally, ensure that you're importing Common.css by placing the following line at the very top of MediaWiki:Wikia.css (if it's not already there):

Please note that  support is inconsistent across browsers, and loading multiple font files has quite an impact on page loads.
