Lausanne Collegiate School

Lausanne Collegiate School (/lɑːzæn/; previously Lausanne School for Girls) is an independent, coeducational college-placement school in Memphis, Tennessee. With grades for pre-kindergarten through twelfth grade, the school has a sizable international population, with foreign nationals comprising 1⁄3 of the student body, representing 68 different countries.

With a 98-year history beginning in 1926, the previously single-sex boarding school has become a co-educational day school. An International Baccalaureate (IB) school since 2009, Lausanne adopted the program for all grades in 2018. In 2017 it partnered with Fujian's Xiamen #1 School to open another fully-IB school in Xiamen, China.

The international school has adopted contemporarily-new methods and attitudes throughout the years. The current campus has specially designed playground equipment, supports several academic and athletic teams, and was a filming location for 1993's The Firm.
