Campo Grande, Urban park in central Valladolid, Spain.

Campo Grande is an urban park in central Valladolid with pathways, gardens, and water features surrounded by three main avenues of the city. The space covers over 100,000 square meters with several defined areas for walking and sitting.

The land was a communal field used for pasture and threshing from the 15th century, and duels were fought there after Fernando IV granted ground for a challenge in the early 14th century. In 1787, under Carlos III, the first tree planting turned it into a garden. It was officially named Campo de Marte on 2 October 1843 after Napoleon's troops camped there in 1808.

The park's name comes from its centuries-old role as a communal field, called Campo de la Verdad from the 15th century after a duel fought there under Fernando IV. Today a pheasantry, an aviary and a pigeon loft run by the Club Colombófilo de Castilla keep peacocks, pheasants and pigeons among the park's most visible residents.

There are multiple entrances around the park, with the main one at Plaza Zorrilla. It is easily accessible by bus and located south of the city center.

The park was a treeless open ground until 1787, when planting began under the protection of King Carlos III. Before that it served for centuries as communal pasture and threshing floor, and as the duelling ground that gave it the name Campo de la Verdad.
