Charles Ramsay Rinehart (December 31, 1875 – October 30, 1933) was an American football player, engineer and businessman.

[1] Rinehart attended Lafayette and played right guard on the school's 1896 team, under coach Parke H. Davis.

Thirty-seven years later, the two teams were named co-national champions for the season by Coach Davis, who had become the sport's pre-eminent historian.

[1] From 1898 until 1900, Rinehart played professional football for the Greensburg Athletic Association.

[6] He also played, against the Greensburg Athletic Association's wishes, in pro football's very first all-star game as a member of the 1898 Western Pennsylvania All-Star football team, which played against the Duquesne Country and Athletic Club on December 3, 1898, at Pittsburgh's Exposition Park.
