Check out this WP Google Fonts.
The WP Google Font plugin makes it even easier to use Google’s free service to add high quality fonts to your WordPress powered site. Not only does this plugin add the necessary Google code, but it also gives you the ability to assign the Google fonts to specific CSS elements of your website from within the WordPress admin. Or if you would rather, you can target the Google fonts from your own theme’s stylesheet.
The Google Directory has hundreds of great fonts, and the selection is steadily growing. As new fonts are added, we will release updates to the plugin quickly so you can start using new fonts as they become available. It truly is an exciting time to be creating websites, and I hope this plugin helps you create some great stuff.
