Robert William Meusel was an American baseball left and right fielder who played in Major League Baseball (MLB) for eleven seasons from 1920 through 1930, all but the last for the New York Yankees. He was best known as a member of the Yankees' championship teams of the 1920s, nicknamed "Murderers' Row", during which time the team won its first six American League (AL) pennants and first three World Series titles.

Murderers' Row were the baseball teams of the New York Yankees in the late 1920s, widely considered some of the best teams in history. The nickname is in particular describing the first six hitters in the 1927 team lineup: Earle Combs, Mark Koenig, Babe Ruth, Lou Gehrig, Bob Meusel, and Tony Lazzeri.
