Bernard Keith Allen (born April 16, 1939) is an American former Major League Baseball player for the Minnesota Twins, Washington Senators, New York Yankees, and Montreal Expos.

The Minnesota and Notre Dame victories were both on the road, while the win over Ohio State earned Allen Sports Illustrated's Offensive back of the Week.

Allen signed with the Minnesota Twins and played 80 games for Class A Charlotte before being promoted to Major League Baseball.

He spent the 1963 off-season as an assistant football coach under Jack Mollenkopf, where he tutored a young Bob Griese.

After five seasons with the Senators which moved to the Dallas–Fort Worth metroplex to become the Texas Rangers, he was dealt to the New York Yankees for Terry Ley and Gary Jones at the Winter Meetings on December 2, 1971.
