Ruy González de Clavijo (died 2 April 1412) was a Castilian traveler and writer. In 1403–1405, Clavijo was the ambassador of Henry III of Castile to the court of Timur, founder and ruler of the Timurid Empire. A diary of the journey, perhaps based on detailed notes kept while traveling, was later published in Spanish in 1582 (') and in English in 1859 (Narrative of the Embassy of Ruy Gonzalez de Clavijo to the Court of Timour at Samarcand AD 1403–6).

Clavijo was a member of a prominent noble family, but little is known about his life; his date of birth is unknown. He was a native of Madrid</blockquote>At the time, Timur was holding a great gathering or kurultai in anticipation of his invasion of China (which was aborted after his death).
