Harry Arthur "Cookie" Lavagetto (December 1, 1912 – August 10, 1990) was a third baseman, manager and coach in American Major League Baseball. He is most widely known as the pinch hitter whose double ruined Bill Bevens' no-hitter in Game 4 of the 1947 World Series and gave his Brooklyn Dodgers a breathtaking victory over the New York Yankees, a game known as The Cookie Game.

On October 3, 1947 at Ebbets Field, Bevens was ahead 2-1 going into the bottom of the ninth inning with two outs. He had surrendered no hits — an unprecedented World Series achievement at the time — but two runners were on base from Bevens' ninth and tenth base on balls of the game. Lavagetto was summoned by Dodger pilot Burt Shotton to hit for Eddie Stanky and he cracked an opposite-field double to break up the no-hitter and score the two Dodger runners for a 3-2 Brooklyn win. It was Lavagetto's only hit of the series (won by the Yankees in seven games) and his last as a big leaguer.

Lavagetto was born in Oakland, California. Nicknamed "Cookie" after an owner of the Oakland Oaks, his first professional team, Lavagetto played ten seasons in the National League with the Pittsburgh Pirates (1934–36) and Dodgers (1937–41, 1946–47). He missed four full seasons due to military service during World War II. A right-handed batter and thrower, Lavagetto batted .269 in 1,043 games; his best season was 1939, when he hit .300 with 87 runs batted in for Brooklyn.
