Paul Chang-Ha Lim (Korean: 임창하; born April 29, 1967) an American ecclesiastical historian who serves as Professor of the Humanities at The Hamilton Center for Classical and Civic Education at the University of Florida.

His main research involves the intellectual history and historical theology of Reformation and post-Reformation England.

[4] Lim is known for his work on Richard Baxter, the celebrated seventeenth-century English Puritan.

[7][8] Jonathan Sheehan at UC Berkeley writes, "Paul Lim's erudite book demonstrates just how challenging it was when, during the English seventeenth century, Christianity's central mystery of the Trinity moved to the center of political, cultural, and religious controversies.

With enormous theological and scriptural learning, Lim lets us see these controversies from the inside.
