John Joseph Rodriguez (born January 20, 1978) is a retired Major League Baseball Player.

He was traded to the St. Louis Cardinals later that year and forced a major league call-up to replace the injured Reggie Sanders by hitting .342 with 17 home runs in 34 games with Triple-A the Memphis Redbirds.

On July 20, 2005, Rodriguez hit his first career home run off Ben Sheets of the Milwaukee Brewers.

On November 30, 2007, the Cardinals designated Rodriguez for assignment, removing him from the 40-man roster to make room for newly acquired shortstop, César Izturis.

On June 8, Rodriguez signed a minor league contract with the New York Mets and was assigned to Triple-A New Orleans.
