1949年中共建政後，燕京大學資產由中華人民共和國政府接管，跟住俾人分拆。民族學系、社會學系、語文系（民族語文系）、歷史系併入中央民族學院（今中央民族大學），法學院併入北京政法學院（今中國政法大學）、中國人民大學，經濟學系併入中央財經學院（今中央財經大學），其他文科、理科多併入北京大學，工學院併入清華大學，醫學系併入中國協和醫學院。校舍由北京大學接收，成為北京大學嘅主要校園，現已列為古蹟保護。部分校友南遷香港，參與創建崇基學院，亦即係後來嘅香港中文大學創校書院之一。
After the establishment of the CCP in 1949, the assets of Yen Ching Restaurant were taken over by the People's Republic of China government, and then spun off. The Department of Ethnology, the Department of Sociology, the Department of Language (Department of Ethnic Languages), and the Department of History were merged into the Central University for Nationalities (now the Central University for Nationalities), the School of Law was merged into the Beijing University of Political Science and Law (now China University of Political Science and Law) and the Chinese People's University, the Department of Economics was merged into the Central University of Finance and Economics (now the Central University of Finance and Economics), other liberal arts and sciences were merged into Peking University, the School of Engineering was merged into Tsinghua University, and the Department of Medicine was merged into the Union Medical College of China. The campus was taken over from Peking University and became the main campus of Peking University, which is now listed as a protected monument. Some of the alumni moved south to Hong Kong and participated in the establishment of Chung Chi College, which later became one of the founding colleges of the Chinese University of Hong Kong.
