Jorge Moises Piedra (born April 17, 1979) is a former Major League Baseball outfielder.
On April 11, 2005, Piedra became the second baseball player after Alex Sanchez to be suspended for testing positive for illegal performance-enhancing drugs under Major League Baseball's new drug policy. He was suspended for 10 days without pay, as MLB's policy dictated for a first offense until November 2005. First offenses since that time now result in 80-game suspensions.
He signed a minor league contract with the Oakland Athletics on June 12, 2007.
On January 4, 2008, Piedra signed a minor league contract with the Florida Marlins with an invitation to spring training. He was released on March 9, 2008.
