The Lake County News-Sun is a regional newspaper based in Gurnee, Illinois, United States, that predominantly covers news for Lake County, Illinois, a part of the Chicago metropolitan area.

While it once covered news in the region almost exclusively (it staved off a challenge from the Tribune when it opened a Lake County bureau).

it has encountered a significant challenge from the Daily Herald since 2000 when that paper opened its Lake County bureau.

In 1971 "Waukegan" was dropped from the masthead and the hyphen was removed in 1997 to bring the name to its current iteration of News Sun.

The size and image change is the biggest transformation the paper has encountered in its long community history.
