Daniel Ray Jennings (born September 16, 1960) is an American professional baseball manager and executive.

Jennings attended Satsuma, Davidson and Fairhope High Schools in Alabama while his father, Don, moved between baseball coaching jobs.

The Mariners promoted him to crosschecker in 1995, and he accepted a job with the Tampa Bay Devil Rays as their scouting director later that year.

It was described in Business Insider as "shocking," in Sports Illustrated as "weird," on Grantland as "utterly baffling" and in USA Today as "bizarre" and optically "problematic" for the troubled Marlins front office.

They unsuccessfully argued that the $100,000 salary the Nationals were paying Jennings was too low for his responsibilities and not enough to offset the $1.5 million the Marlins still owed him.
