2015 World Masters Athletics Championships

45.7879°N 4.7976°E / 45.7879; 4.7976 (Stade de Balmont)

2015 World Masters Athletics Championships is the 21st in a series of World Masters Athletics Outdoor Championships that took place in Lyon, France from 4 to 16 August 2015. This was the last odd year of the biennial Championships; beginning in 2016, the Championships will be held in even-numbered years. The change was made to avoid conflict with the quadrennial World Masters Games, which had been held in odd-numbered years since 2005.

The main venue was Stade de Balmont (Stade de La Duchère). Supplemental venues included Stade du Rhône (Stade de Parilly) for road races and throwing events, the newly resurfaced Stade Pierre Duboeuf in Bron, the newly resurfaced Stade Laurent Gérin in Vénissieux, and Halle d'athlétisme Stéphane-Diagana as the Centre d'Information Technique. ^{: 14 : 46–51}

The WMA is the global governing body of the sport of athletics for athletes 35 years of age or older, setting rules for masters athletics competition.

In addition to a full range of track and field events, non-stadia events included 8K Cross Country, 10K Race Walk, 20K Race Walk, Half Marathon and Marathon.
