Paul David Serna (born November 16, 1958 in El Centro, CA) is an American former professional baseball player. He played two seasons in Major League Baseball (MLB) for the Seattle Mariners.

Paul was signed as an amateur free agent by Seattle in June of 1980, and by the following September he was in the MLB. Playing mostly shortstop down the stretch, Serna batted .255 with 4 home runs in 30 games. That earned him a shot the following year, and he spent the whole 1982 season in Seattle as a utility infielder. In 68 games that season, he batted .225, with just 3 home runs and 8 RBI.

The following season, Paul was returned to the minor leagues. He played for three more seasons, but never played in the majors again. He coached in minor league baseball after retiring for the Wausau Timbers.

Researcher Gene Leggitt informs Baseball Amore that Paul is not of Italian heritage, resulting in the “Doubtful” notation.
