OK.ru (Russian: Однокла́ссники, English: Classmates) is a social network service for classmates and old friends. It is especially used in Russia and former Soviet Republics. The site was developed by Albert Popkov and launched on March 4, 2006.

The website currently has more than 200 million registered users and 45 million daily unique visitors. Users have to be at least seven years old to create an account. Odnoklassniki also currently has an Alexa Internet traffic ranking of 56 worldwide and 7 for Russia. Revenues in the first quarter of 2008 for Odnoklassniki amounted to $3.3 million. Odnoklassniki is the second most popular social network in Russia, behind VK (VKontakte) but ahead of Facebook which is in 3rd place.

History: On March 26, 2006, the Odnoklassniki project was launched.

The creator of the site, Popkov Albert, who lives in London and works in the field of telecommunications, took part in the creation of similar projects in other European countries. From March to November 2006, the project existed as a hobby and was commercially mentioned only in a friendly advertising agency as a platform for advertising. The number of users who registered on the site grew exponentially, so the founder of the project decided to create a separate legal entity.
