Theodore Goldsmith Joslin (February 28, 1890 – April 12, 1944) was the second White House Press Secretary under President Herbert Hoover from 1931 until 1933.

After graduating from high school, he took a job with the Boston bureau of the Associated Press (AP), rising from office boy to correspondent.

In 1939, he became director of public relations for the DuPont Company, holding that post until he died in his office of a heart attack.

During his tenure as presidential press secretary, Joslin struggled to improve Hoover's public image.

Much of what he omitted was later published by Timothy Walch and Dwight M. Miller in Herbert Hoover and Franklin D. Roosevelt: A Documentary History (1998).
