Donald Hassett Lucy (born August 8, 1982) is a former Major League Baseball catcher.

After his junior year, he was selected by the Chicago White Sox in the 2nd round (59th overall) in the 2004 Major League Baseball Draft.

Lucy made the White Sox opening day roster for the 2010 season after backup catcher Ramón Castro bruised his heel in a spring training game and was placed on the DL.

Lucy hit his first home run, a solo shot, on April 15, 2010 off Toronto Blue Jays starting pitcher Dana Eveland.

On May 3, 2010 Donny was optioned to the White Sox Triple-A team, Charlotte Knights, due to Ramon Castro being activated from the 15-day disabled list.
