Joshua David Willingham (born February 17, 1979 in Florence, Alabama) is an American Major League Baseball player for the Washington Nationals. He is nicknamed "The Hammer." A power-hitting prospect for six minor league seasons, Willingham has been held back by his injuries. Drafted as a shortstop, and coming up as a third baseman, he moved behind home plate to become a catcher. He is now the primary right fielder for the Nationals.

Willingham was drafted by the Florida Marlins in the 17th round of the 2000 amateur draft. He was one of several hopeful 2006 National League Rookie of the Year Candidates with the Florida Marlins, along with shortstop Hanley Ramirez and first baseman Mike Jacobs, as well as many other of the Marlins' prospects such as Dan Uggla. On April 4, Willingham recorded his first career multi-homer game, launching two against the Houston Astros. In 2007 Willingham hit 21 home runs with 89 runs batted in.

On November 11, 2008, Willingham was traded to the Washington Nationals along with pitcher Scott Olsen for Emilio Bonifacio, Jake Smolinski, and P.J. Dean .
