Gaspar de Guzmán, Count-Duke of Olivares, on Horseback (Spanish: Gaspar de Guzmán, conde-duque de Olivares, a caballo) is an oil on canvas painting by Spanish painter Diego Velázquez, made around the year 1636. It has been in the Museo del Prado in Madrid since its inauguration in 1819.

This painting is an exception for the style of Velázquez as its design and color are more vigorous and pompous than his usual more somber portraits. The object of the work was to validate the power of Gaspar de Guzman, Count of Olivares and Duke of Sanlúcar la Mayor, known as the Count-Duke of Olivares, the chief minister under Philip IV of Spain, a Spanish nobleman and influential politician.
