Robert Samuel Houston (August 7, 1820 – January 5, 1902) was an American dairy farmer and Wisconsin pioneer.

He worked for one employer in Meriden, Connecticut, from 1851 until moving to Wisconsin in September 1857, eventually settling on a farm in Pleasant Prairie, where he took up dairy farming, selling butter and cheese (winning medals with both); and raised hay, corn and oats.

The coalition won the election for Governor of Wisconsin and secured Democratic control of the Assembly for the first time since before the Civil War.

[4] This was an especially important committee during this legislative term, as railroad regulation was one of the key issues of the Reform coalition.

In the end, Houston was paid a small amount for his loss, but he continued his challenge and prepared a bill of damages, demanding full compensation.

His paternal grandfather, John Houston, served in the New Hampshire militia during the American Revolutionary War.
