Count Giovanni Giorgio Trissino (22 July 1877 – 22 December 1963) was an Italian horse rider who won Italy's first ever gold medal at the Olympic Games in Paris 1900.

[1][2] In Paris he tied to the gold medal in the high jump event with Dominique Gardères and was fourth in the same competition with a different horse.

At the Summer Olympic Games in Paris 1900, in both competitions he won the two medals on the saddle of Oreste, a horse that was initially due to the great Federico Caprilli, his teacher, who, after sending his horses to France, was recalled by a telegram from the Ministry of War that forbade the expatriation to the military in career following the dissolution of the Chambers.

This situation evidently was not well communicated to the judges of the race and this led to confusion to the point that in some books of gold it was erroneously indicated Caprilli in place of Trissino.

According to some reconstructions Caprilli could indeed have reached Paris in disguise from Turin to complete the preparation of his horses, giving rise to fictional voices related to his active participation in competitions.
