Neenah is a city in Winnebago County, Wisconsin, United States. The population was 24,507 at the 2000 census. The city is surrounded by, but is politically independent of, the Town of Neenah. Neenah is the southwestern-most of the Fox Cities of Northeast Wisconsin.

Neenah hosts a significant steel and paper industry and is the number one producer of manhole covers in America. The Kimberly-Clark Corporation was founded in Neenah and maintains significant operations there, though its headquarters moved to Dallas, Texas in the 1980s following a dispute over taxes between the CEO and the governor of Wisconsin.

Perhaps the most famous resident of Neenah was film director Howard Hawks, whose mother was a Neenah native. Her husband Frank Hawks moved to Neenah from Goshen, Indiana when Howard was an infant. The family resided in Neenah in a house they had built on Wisconsin Avenue, then Neenah's most prestigious thoroughfare, until Mrs. Hawks' best friend Theda Clark, a Kimberly-Clark heiress, died young (posthumously endowing Neenah's first hospital, Theda Clark Hospital, still in operation today). Mrs. Hawks' grief motivated the family to move full-time to Pasadena, California, where they had previously wintered.

Neenah's Bergstrom-Mahler Museum has a world-renowned collection of glass art, comprising over 3,000 pieces, concentrated in historic and art paperweights and Germanic glasswork.
