David William Shean (July 9, 1883 – May 22, 1963) was an American professional baseball second baseman.

A graduate of Fordham University, Shean was a well-traveled utility who spent 14 years in baseball, nine of them in the major leagues.

His most productive season came in 1918 with Boston, when he posted career-numbers in batting average (.264) and runs (58), while leading the American League hitters with 36 sacrifice hits.

Following his baseball career, Shean was president of Nathan Robbins Company, a poultry concern.

Shean died at the age of 79 in Boston, Massachusetts, after suffering injuries in an automobile accident.
