Lakeside is an unincorporated area and census-designated place in Clay County, Florida, United States.

To the north is the Bellair-Meadowbrook Terrace CDP, and to the southeast, across Doctors Lake, an inlet of the St. Johns River, is Fleming Island.

The center, established in 1930 by psychologist Robert Yerkes and Yale University and the Rockefeller Foundation, was the first laboratory in the United States for the study of non-human primates.

Prior to the opening of the facility, Yerkes was engaged in his own research with two great apes, named "Chim" and "Panzee".

Initially designed to house about 25 chimpanzees, researchers worked with an estimated 65 chimps (and possibly more) during the lab's 35-year history.

This location was home to chimpanzees nurtured as humans such as Gua and Viki and other primates from the estate of Madame Rosalia Abreu in Havana, Cuba.

Comically, rumors about the place by some Orange Park residents included those of scientists cross-breeding humans with apes.

The plot of land upon which Yerkes Labs sat was 188 acres (76 ha), about a mile west of Orange Park.

In 1966, the abandoned buildings and adjacent land were purchased by Developer Marvin Wilhite of Ahpla, Inc., who still lives in Foxwood and built other communities such as Foxridge.

Foxwood Center still has some of the original laboratory buildings that once housed the chimps, the grounds caretaker, and administrative offices.
