David Hans Bennett (born November 7, 1945) is a retired American professional baseball player. The right-handed pitcher, listed as 6 feet 5 inches (1.96 m) tall and 195 pounds (88 kg), had a 12-year pro career (1963–74) but appeared in only one Major League game, which was for the 1964 Philadelphia Phillies.
Bennett worked just one inning—the ninth—in relief on June 12 against the New York Mets at Connie Mack Stadium. He allowed a leadoff triple to Joe Christopher, then wild pitched him home. He later allowed a double to veteran Mets' shortstop Roy McMillan, who was left stranded. Bennett struck out Charley Smith and issued no bases on balls. The game, won by the Mets 11–3, had been started by Dave Bennett's older brother and teammate, Dennis, who took the loss.
In 1963, Dave Bennett was signed as an amateur free agent (prior to the establishment of the Major League Draft). He pitched in the Phillies' farm system for seven years before being dealt to the Pittsburgh Pirates organization (with minor leaguer Mike Everett) for catcher Del Bates, on January 28, 1970.
