The DuPage Valley Conference (DVC) is an organization of six high schools in northeastern Illinois, representing seven communities in Chicago's suburbs.

The conference experienced the first membership change in 1983, when Glenbard East High School left the Des Plaines Valley League and joined the DVC, replacing Wheaton-Warrenville High School, which was closed due to low attendance.

At the same time Lake Park High School took the vacant space after leaving the Upstate Eight Conference Valley Division.

The two schools voted unanimously to accept the invitation to the Upstate Eight Conference starting in the 2014–2015 season.

Glenbard North High School declined an invite from the Upstate Eight Conference to join.

DeKalb High School accepted an invitation to join the DVC for the 2019-2020 season following the break-up of the Northern Illinois Big 12 Conference.
