Robert Boyd Wentworth (January 18, 1827 – August 9, 1914) was an American newspaper publisher and Republican politician.

[3] In 1857, he relocated to Portage, Wisconsin, in Columbia County, and purchased a paper called the Independent from Julius C. Chandler.

He renamed it the Portage City Record and published for several years in partnership with Andrew Jackson Turner and Moses M. Davis.

[2] After selling his stake in the Record, Wentworth pursued other business ventures, building a grain elevator on the bank of the ship canal between the Fox and Wisconsin rivers.

He subsequently operated a successful grain trade for several years, and through that interest developed into shipping, creating the Portage and Green Bay Transportation Company.
