The Irish National Cycling Championships are annual cycling races to decide the Irish cycling champion for several disciplines, across several categories of rider.

Seamus "Shay" Elliott was an Irish road bicycle racer, Ireland's first major international rider, with a record comparable only to Sean Kelly and Stephen Roche. He was the first Irish person to ride the Tour de France, first to win a stage, and first to wear the yellow jersey, and first English speaker to win stages in all the Grand Tours.
