The 2026 Diamond League will be the seventeenth season of the annual series of outdoor track and field meetings, organised by World Athletics. The competition was a revision to the top level athletics series since Diamond League foundation in 2010. The number of Diamond Discipline events was 32. Each meeting hosted a number of Diamond Discipline events and some of these events would not be broadcast. Events losing Diamond Discipline status would feature on the World Athletics Continental Tour, the second tier of track and field meetings.
