Thomas George McNall (1874–1953) was a merchant and political figure in Saskatchewan, Canada.
Around 1900, he moved to Toronto, where he was employed with George Weston's company.
He bought out the branch in 1914 and opened his own wholesale business.
In 1950, he sold the business to the Hudson's Bay Company but continued on as corporate director.
McNall served on Regina city council from 1926 to 1944.
