Stephen Andrew Cardullo (born August 31, 1987 in Hollywood, FL) is a professional baseball outfielder and first baseman who played for the Colorado Rockies of Major League Baseball (MLB) in 2016 and 2017. Stephen played college baseball for the Florida State Seminoles.

Cardullo attended St. Thomas Aquinas High School in Fort Lauderdale, Florida. He was not recruited to play college baseball, but after a tryout became a walk-on for the Florida State Seminoles baseball team at Florida State University. After receiving little playing time as a freshman and a sophomore, he began his junior year as the Seminoles' starting first baseman before shifting to shortstop. He batted .376 with 10 home runs and 51 runs batted in, and was named a First-Team All-American. In 2009, he played collegiate summer baseball with the Harwich Mariners of the Cape Cod Baseball League.

The Arizona Diamondbacks selected Cardullo in the 24th round of the 2010 Major League Baseball draft. Stephen spent the 2010 and 2011 seasons in rookie ball with the Missoula Osprey but on March 20, 2012, he was released by the Diamondbacks organization.

Cardullo signed with the Rockland Boulders of the Can-Am League for the 2013 season. On January 6, 2016, he signed a minor league contract with the Colorado Rockies organization. He would go on to become the first alumni of the Rockland Boulders in the Can-Am Association to make the major leagues.

Stephen was called up to the major leagues for the first time on August 26, 2016. He hit his first Major League home run against Casey Fien in the first game of a doubleheader against the Los Angeles Dodgers on August 31, 2016, his 29th birthday, and his first grand slam in the second game against Bud Norris. On December 2, 2016, Cardullo was non-tendered by the Rockies after hitting .214/.254/.411 with 2 home runs and 6 RBI in 27 games.
