Port Barrington (also referred to as Fox River Valley Gardens or FRG) is a village in Lake and McHenry counties in the U.S. state of Illinois.

Homeowners in the new Riverwalk subdivision claimed that their home values fell significantly and immediately when their addresses were changed to "Fox River Valley Gardens".

This prompted residents in the Riverwalk section of the village to express their objection to what appeared to be a "bait and switch" in the change of mailing address.

In September 2002, the village board voted 4–3 to re-incorporate and change the community's name to "Port Barrington".

However, several addresses in the older section of the village are still listed under the name Fox River Valley Gardens.

In addition, many road signs and maps continue to use the community's original name, as do the local police and fire departments.

At Christmas, a Santa Claus arrives in a parade through town with an escort of fire engines, McHenry County Sheriff and car loads of people throwing candy to kids waving from their homes and yards.
