Henry Colden Antill Harrison (16 October 1836 – 2 September 1929) was an athlete and Australian rules footballer who played a leading role in pioneering the sport.

Within a year, Harrison joined him in promoting the new code, and quickly emerged as a leading player, celebrated for his speed, strength and courage.

He oversaw an 1866 revision of the code that formalised the running bounce, and captained Melbourne and Geelong before retiring from playing in 1872.

Nonetheless, Harrison remained for many years the sport's "most formidable voice", and the honorific title of "Football's Foster Father" has been applied to him by some modern historians.

In about 1837, the family moved to the Port Phillip District, and took up land on the Plenty River about 20 miles (32 km) from Melbourne.

On 8 May 1866, Harrison chaired a meeting of club delegates in order to draft a revised set of rules, and his changes were unanimously agreed upon.

In 1908, a newly completed grandstand at the Melbourne Cricket Ground (MCG), designed by William Pitt, was named after Harrison.

A building on Spring Street, Melbourne was purchased by the VFL in the 1920s to serve as their new headquarters,[2] and was named Harrison House in his honour.

The Harrison Medal, which is awarded to the best player in Division 2 at the AFL Under 18 Championships is often mistakenly thought to be named in his honour.
