The year 2015 in equestrianism saw numerous international competitions across dressage, eventing, jumping, reining, and endurance under the governance of the Fédération Équestre Internationale (FEI). Highlights included the 2015 FEI Nations Cup Dressage (March–July), with wins by Dominique Filion, Laura Graves, Patrick Kittel, Kristina Bröring‑Sprehe, and Carl Hester in individual events, and national teams from Germany, the USA, the Netherlands, Sweden and Denmark securing victories. The 2015 FEI Nations Cup Eventing spanned March to October, featuring top performances by Michael Jung, Ingrid Klimke, and Nicola Wilson, and culminating in team triumphs from France, Great Britain, Germany, and Ireland. Key championships included the 2015 European Dressage Championships in Aachen (August), which served as a qualifier for the 2016 Olympics, and the 2015 Equestrian World Cup Final in April. The season also included regional events in reining, show jumping, and endurance.
