Knowles Memorial Chapel, built between 1931 and 1932, is an historic Mediterranean Revival building located on the campus of Rollins College in Winter Park, Florida, in the United States.

In the summer of 2007 it underwent a masonry restoration paid for by a trust set up by Frances Knowles Warren.

At the same time the Dyer firm also built and installed a "completely new, free-standing antiphonal organ at the rear of the balcony and surrounding the Rose Window."

Deeply involved in the work by the Dyer firm was its associate, John J. Tyrrell, former president of Aeolian-Skinner.
