The Renren Network ("everyone network"), formerly known as Xiaonei Network or "on-campus network" is a Chinese social networking site with an interface similar to that of Facebook. It is popular among college students in China.

According to Xiaonei, as of July 2008, Xiaonei was "China's largest online community website among universities" with more than 22 million active users and an estimated 40 million users who have registered their real names. Thus, Xiaonei is widely considered to be the most powerful student social network service in Mainland China, especially among university students.
