Warren E. Giese (July 14, 1924 – September 12, 2013) was an American state legislator in South Carolina and a college football coach.

At South Carolina, Giese employed a conservative, run-first game strategy, but he enthusiastically adopted the two-point conversion when it was made legal in 1958.

That year, he also correctly predicted the rise of special teams after the NCAA relaxed its player substitution rules.

[9] In March 1951, Giese declined the head coaching position at Central Michigan University, for which he had already been approved by the school administration, after Maryland offered him a pay raise.

"[12] When Giese took over in 1956, at least 51 South Carolina players were being paid, in violation of National Collegiate Athletic Association (NCAA) rules.

The Gamecocks' star running back, Alex Hawkins, admitted, "Every school that recruited me had some kind of financial offer."

[2] That season, the NCAA implemented the two-point conversion rule, and Giese enthusiastically adopted it as part of his game strategy.

[12] That season, the NCAA loosened its rules regarding player substitutions, and Giese correctly predicted the future rise of a "third platoon", distinct from the offensive and defensive units of two-platoon football.

[12] After his relief as head coach, Giese remained the South Carolina director of athletics for an additional year.

[16] One of his sons, W. Barney Giese, who attended the University of South Carolina as an undergraduate and for law school, served as the solicitor (district attorney) for Richland County from 1995 to 2011.
