Harry Emerson Rowbottom (November 3, 1884 – March 22, 1934) was an American businessman and Republican politician. He was elected to the United States House of Representatives from Indiana in 1924 and served three terms from 1925 to 1931. He was defeated for re-election in 1930 and subsequently convicted of accepting bribes, abruptly terminating his political career.

Rowbottom was born in Aurora, Indiana, and moved with his parents to Ludlow, Kentucky, in 1885. In Kentucky he attended the common schools, graduated from Ludlow High School in 1901, and subsequently attended Kentucky State College at Lexington from 1902 to 1904.^{[citation needed]}

From 1904 to 1907 Rowbottom worked selling lubricating oils. He graduated from the Cincinnati Business College in 1907, where he studied accountancy. Following graduation, Rowbottom found work as an auditor in Cincinnati from 1907 to 1910 and Chicago from 1910 to 1912. He moved to Evansville, Indiana, in 1913 and was employed as chief clerk for the Indiana Refining Company from 1913 to 1918.^{[citation needed]}

Rowbottom was elected to the Indiana House of Representatives in 1918, serving two consecutive terms from 1919 to 1923. His legislative service coincided with the end of World War I and the Red Summer of 1919, which witnessed the rise of the second Ku Klux Klan. Like many prominent Indiana Republicans, Rowbottom sought out the Klan's electoral support and proudly boasted of his membership in the organization.

He died in Evansville on March 22, 1934, and is interred in Locust Hill Cemetery.^[6]
