Henry Greenleaf Webb (January 24, 1826 – August 28, 1910) was an American lawyer, politician, and pioneer of Wisconsin and Kansas.

Henry G. Webb was born January 24, 1826, in Ridgebury Township, Bradford County, Pennsylvania.

As a young man he went to study law under judge John C. Knox and was admitted to the bar at Wellsboro, Pennsylvania, in September 1848.

His candidate, James Buchanan, won the presidency, but the Republican electoral slate was chosen in Wisconsin.

[4] Shortly after the election, Webb moved to Wautoma, Wisconsin, where his brother William had settled, and began affiliating with the Republican Party.

In the 1860 election, Webb was the Republican nominee for Wisconsin State Assembly in the Waushara County district.

[5][6] After the outbreak of the American Civil War during the 1861 session, Webb began working to raise a company of volunteers for the Union Army.

[9] During the 1866 legislative session, redistricting occurred and Webb ran for re-election that year in the new 29th Senate district, which then comprised Green Lake, Marquette, and Waushara counties.

[6] Shortly after the end of the 1868 legislative session, Webb moved to Kansas along with his brother, William, and their families.

In 1903, he retired due to poor health and moved to Houston, Texas, believing the warmer climate would be beneficial to his constitution.

During a 1906 visit to friends in Yellville, Arkansas, he felt such improvement in his health that he decided to permanently relocate there.

In April 1866, Webb remarried with Amanda Jean Gower of Pennsylvania, but there were no known children of the second marriage.
