John George Brandt Jr. (born April 28, 1934) is an American former professional baseball outfielder, who played in the major leagues for the St. Louis Cardinals (1956), New York / San Francisco Giants (1956–1959), Baltimore Orioles (1960–1965), Philadelphia Phillies (1966–1967), and Houston Astros (1967).

Brandt made his big league debut on April 21, 1956, against the Milwaukee Braves at Sportsman's Park, then was traded to the New York Giants almost two months later.

In 1959, he won a Gold Glove for his stellar play as the San Francisco Giants' regular left fielder, then was traded to Baltimore, where he would have his most productive years.

He drove in the only run in a rare battle of complete game one-hitters between Orioles left-hander Frank Bertaina and Kansas City Athletics southpaw Bob Meyer.

Teammate Bob Saverine entered the 0–0 game in the bottom of the 8th inning, as a pinch runner for John Orsino, who had doubled.
