The Gelderland or Gelderlander is a heavy warmblood breed of horse that was developed in the province of Gelderland in the Netherlands. The Gelderlander along with the similar Groninger horse from the north provided the foundation for the Dutch Warmblood. Originally bred to be a stylish carriage horse versatile enough to work on the farm the Gelderlander declined in popularity in the middle of the 20th century.
