Jeffrey Charles D'Amico (born December 27, 1975 in St. Petersburg, FL) is a former professional baseball pitcher from 1996 to 2004. Jeff, sometimes nicknamed "Big Daddy" due to his six-foot-nine stature, was a starting pitcher who played for the Milwaukee Brewers, New York Mets, Pittsburgh Pirates, and Cleveland Indians of Major League Baseball (MLB).

Jeff was selected by the Milwaukee Brewers in the first round of the 1993 Major League Baseball Draft. After three seasons in the minor leagues, he made his debut on June 28, 1996, and spent the next six years with the Brewers. After missing all of 1998 and most of 1999 due to shoulder surgery, he had a career year in 2000.

That season, his ERA hovered around 2.00 for much of the season and he contended for the NL ERA title. Needing just a few innings to qualify for the title on his last start of the season, he surpassed the 162 innings minimum threshold, but in the process gave up enough runs to lose the title. Jeff finished third, behind Kevin Brown and Randy Johnson.

On April 12, 2001, he hit the first triple at Miller Park after Houston's centerfielder Richard Hidalgo crashed into the wall trying to flag down the fly ball to center. Jeff was also a very good fielding pitcher. In 784 innings pitched over 139 games, he committed only one error in 116 total chances for a .991 fielding percentage.

Not to be confused with Jeffrey Michael DAmico, who pitched for the Royals in 2000.
