Samuel Alexander Boyle Jr. (November 28, 1876 – October 30, 1923)[1] was an American college football player and coach.

He served as the head football coach at the Virginia Military Institute (1898–1899), Pennsylvania State University (1899), and Dickinson College (1900), compiling a career coaching record of 14–12–1.

Boyle played end for the University of Pennsylvania[2] and was declared a first-team All-American in 1897.

[6] After one year at Penn State, Boyle became the second head football coach (or at least, the second coach on record) for the Dickinson College Red Devils in Carlisle, Pennsylvania and he held that position for the 1900 season.

[13] Boyle died on October 30, 1923, at his home in Rydal, Pennsylvania, after suffering from tuberculosis for more than five years.
