George Stewart Henry was a farmer, businessman and politician in Ontario, Canada. He served as the tenth premier of Ontario from 1930 to 1934. He had acted as minister of highways while Ontario greatly expanded its highway system. Henry continued the expansion as premier, but his party did not provide relief during the Great Depression and lost the 1934 election.

The premier of Ontario is the head of government of Ontario. Under the Westminster system, the premier governs with the confidence of a majority the elected Legislative Assembly; as such, the premier typically sits as a member of Provincial Parliament (MPP) and leads the largest party or a coalition of parties. As first minister, the premier selects ministers to form the Executive Council, and serves as its chair. Constitutionally, the Crown exercises executive power on the advice of the Executive Council, which is collectively responsible to the legislature.
