John Owsley Manier (March 18, 1887 – September 1, 1956) was an American college football player and coach and physician.

He was a "great plunging back"[2] who in which every year he played at Vanderbilt was both a member of Southern Intercollegiate Athletic Association (SIAA) championship teams and selected All-Southern.

[3] In 1915, John Heisman said Vanderbilt's three greatest players ever were Manier, Ray Morrison, and Bob Blake.

"But his effectiveness at Pennsylvania was lessened by the attempt of the coaches to change his style of bucking a line from the low, plunging dive to running into it erect, knees drawn high and great dependence upon his companion backs to "hike" him.

[14] The Nashville Banner reported his death in 1956: "Vanderbilt University loved him, and no alma mater has been better served by an alumnus.
