The 2003 IAAF World Outdoor Meetings was the first edition of the annual global series of one-day track and field competitions organized by the International Association of Athletics Federations (IAAF).
[1] The Herculis meeting was dropped from the Golden League circuit as it was given the role of host of the new series-ending IAAF World Athletics Final, which had an expanded programme of events compared to the IAAF Grand Prix Final of previous years.
The changes to the tiers of the series saw the meeting schedule expanded by nearly 50%.
Performances on designated events on the circuit earned athletes points which qualified them for entry to the 2003 IAAF World Athletics Final, held on 13–14 September in Monaco.
The world rankings system formed the selection criteria for entry to the World Athletics Final rather than exclusively placings at IAAF Grand Prix meetings.
