John Joseph Daly (22 February 1880 – 11 March 1969) was an Irish runner who won a silver medal in the steeplechase at the 1904 Summer Olympics.

Daly competed in the 2590 metre steeplechase at the 1904 Summer Olympics held in St Louis, United States and won the silver medal.

In what became the first political protest in modern Olympic history, O'Connor scaled the flagpole, took down the Union Jack, and replaced it with the Irish flag.

As officials and stadium security moved to intervene, Daly stood guard at the bottom of the pole with Irish-American wrestler Con O'Kelly, with Irish and American fans invading the field to assist them.
