David Beals Becker (July 5, 1886 – August 16, 1943) was an American outfielder in Major League Baseball from 1908 to 1915.

From 1908 to 1915, Becker played for the Pittsburgh Pirates, the Boston Doves, the New York Giants, the Cincinnati Reds, and the Philadelphia Phillies.

He was a fair fielder and, as a left-handed batter who had trouble with southpaw pitching, he was often platooned to face right-handers.

On June 9, 1913, he tied a 20th-century major league record with two inside-the-park home runs in one game.

On episode #1309, (airing March 23, 2009) of PBS's Antiques Roadshow, a man who claimed to be Becker's great-great nephew brought two photographs and a uniform belonging to Becker to the show for appraisal.
