Vernon Van Duke Duncan (January 6, 1890 – June 1, 1954) was a Major League Baseball outfielder.

He began his major league career late in the 1913 season with the Philadelphia Phillies, then jumped to the new Federal League during the offseason.

He spent the next two seasons as a starting outfielder for the Baltimore Terrapins, playing mostly as a center fielder.

Although he continued to play professionally in the minor leagues until 1927, Duncan never played in the majors again.
