George S. Kariotis (February 22, 1923 – July 7, 2013) was an American businessman who was the Republican Party nominee for Governor of Massachusetts in 1986.
He graduated from Northeastern University in 1940, and then served in the United States Navy during World War II.
Kariotis ran a write-in campaign in the 1986 Republican primary for Massachusetts governor, and finished third with 17% of the vote.
He became the nominee when the two candidates who finished ahead of him Royall H. Switzler and Greg Hyatt both withdrew from the race due to personal scandals.
Kariotis, 90, died in his sleep on July 7, 2013 at his home in Eastham, Massachusetts.
