Ann Rosener (November 25, 1914 – May 19, 2012) was an American photojournalist who is remembered for her photographs of home front activities for the Farm Security Administration and the United States Office of War Information in 1942–43.

The daughter of well-to-do parents in the San Francisco area, Rosener graduated from Smith College in 1935.

Her images cover women handling men's jobs and girls producing gas masks or working as mechanics.

She also illustrated stories showing how Americans were working together to build tanks and planes, irrespective of creed or colour.

[1] Her obituary in the San Francisco Chronicle refers to her striking photos highlighting the sudden breakthrough of women in industry, performing work that had long been a male preserve.
