José Celestino Mutis (Cádiz, Spain, April 6, 1732 – Bogotá (now in Colombia), September 11, 1808) was a Spanish botanist and mathematician.

He was born in Cádiz and baptized with the name José Celestino Bruno Mutis y Bosio. He began his medical studies at the College of Surgery in Cádiz, where he also studied physics, chemistry and botany. He graduated in medicine from the University of Seville on May 2, 1755.

On July 5, 1757 he received his doctorate in medicine. From 1757 to 1760 he was interim professor of anatomy in Madrid. During those same years he continued to study botany at the Migas Calientes Botanical Gardens (now the Real Jardín Botánico de Madrid), and also astronomy and mathematics.

After three years he decided to leave for America, as the private physician of the new viceroy of New Granada, Pedro Messía de la Cerda. He sailed on September 7, 1760, arriving at Santa Fe de Bogotá on February 24, 1761. During the long transatlantic passage he began writing his Diario de Observaciones, which he continued until 1791.
