Samuel Nelson Monteith (November 21, 1862 – October 19, 1949)[1] was an Ontario farmer and political figure.
He served as reeve for Downie Township from 1894 to 1896 and was warden for Perth County in 1897.
An appeal followed and Monteith won the subsequent by-election, losing in 1902 to Valentine Stock.
Monteith defeated Stock in the 1905 election and served as Minister of Agriculture from 1905 to 1908.
The municipality of Monteith in Cochrane District, now part of Iroquois Falls, was named in his honour; it was the site of an experimental farm.
