What are the oldest high school football Thanksgiving rivalries?

Answer 1

There are a couple in the Boston area. One is Wellesley vs Needham. Some of the others over 100 years are Beverly vs Salem.

The oldest high school Turkey Day Game rivalry is in Massachusetts between Needham and Wellesley, dating back to 1882.[citation needed] Currently, Wellesley is leading the rivalry with 58 wins to Needham's 53 with 9 ties in the series. Boston Latin and Boston English have met annually since 1887, the oldest continuous meeting between schools. In Massachusetts, where high school football is not nearly the draw it is in other parts of the country, the Thanksgiving Day game is a long-standing tradition that brings out thousands of alumni and other fans. Virtually every school in the Bay State has a traditional rival and the holiday game is a focal point for all of them, no matter how unsuccessful the regular season may have been.

When it comes to prep schools, Andover and Exeter have the longest standing rivalry dating back to 1878. Not too far behind are Nobles vs. Milton as well as St. Mark's vs. Groton. Both of those games started in 1886.
