The John D. Rockefeller Jr. Library, nicknamed "the Rock", is the primary teaching and research library for the humanities, social sciences, and fine arts at Brown University in Providence, Rhode Island.

The library was named after John D. Rockefeller Jr., who graduated in the class of 1897.

[2] The library houses Brown University's East Asian Collection, which started in 1961 after Charles Sidney Gardner donated about 30,000 volumes, most of them Chinese.

The University began to acquire Japanese works after a grant was received in 1980.

[3] The most recent renovations of the "Rock" include the creation of the David and Laura Finn Reading Room (2009), the Patrick Ma Digital Scholarship Lab (2012) and the main floor reading room (2014).
