Ireland competed at the 2007 World Championships in Athletics in Osaka, Japan.

Despite not winning any medals, the team was thought to have performed excellently by Irish commentators.

[1] Ireland's highest placed finishers were Eileen O'Keefe in the women's hammer throw and Robert Heffernan in the men's 20K walk, both of whom finished in 6th place.

Only one national record was set, by Joanne Cuddihy in the women's 400m semi-final.

Despite none of them making the final, Ireland's sprinters were perhaps the most impressive performers with David Gillick, Paul Hession, Derval O'Rourke and Cuddihy all reaching the semi-finals and being ranked inside the top 16.
