Armstrong Frederick "Klondike" Smith (January 4, 1887 – November 15, 1959) was a Major League Baseball outfielder. He started the last seven games of the 1912 season for the New York Highlanders, who were 50–102 and finished in last place in the American League. The 25-year-old rookie was a native of London. Smith made his major league debut in a September 28 double-header against the Philadelphia Athletics at Shibe Park. His last appearance was on October 5 in a home game against the Washington Senators at Hilltop Park. That was the only game the Highlanders won while Smith was in the lineup.
