Robert Henry Winters PC (August 18, 1910 – October 10, 1969) was a Canadian politician and businessman.

Born in Lunenburg, Nova Scotia, the son of a fishing captain, Winters went to Mount Allison University in New Brunswick, and then to the Massachusetts Institute of Technology to complete his degree in electrical engineering.

He worked for Northern Electric before joining the army in World War II, eventually becoming a lieutenant-colonel.

Defeated along with the St. Laurent government in the 1957 election, Winters entered the corporate world, becoming a chief executive officer at a series of companies.

He was hired as a special advisor to the Newfoundland government to help negotiate the Churchill Falls deal, for which he became highly popular in that province.
