This plugin gives you the ability to limit WordPress admin logins based on the country the visitor's IP address is located in. It uses Maxmind's GeoIP database which comes in a free lite version.

You can choose between a white- and blacklist mode. In whitelist mode only visitors with IP addresses from the configured countries are allowed. In blacklist mode visitors with IPs from the configured countries are not allowed to login.

HELP! I locked myself out! How do I get in again?

No worries! Just add define('LIMIT_LOGIN_COUNTRIES_OVERRIDE', TRUE); to your wp-config.php and you can login again in whichever country you are.
