Clarendon Hills is a village in DuPage County, Illinois, United States.

The area that is now Clarendon Hills was a wide, rolling prairie bordering the east side of Westmont.

Instead, Clarendon Hills was built to resemble nearby Riverside, a planned, park-like suburb designed by Fredrick Law Olmsted in the late 1800s.

In 1961, TWA Flight 529 crashed in Clarendon Hills, killing all 73 passengers on board.
