Xanthus of Lydia (Greek: Ξάνθος, Xanthos) was a native Lydian historian and logographer who, during the mid-fifth century BC, wrote texts on the history of Lydia known as Lydiaca (Λυδιακά). Xanthus also wrote occasionally about geology. It is believed that Xanthus was the earliest historian to have written a significant amount on the topic of Lydian history. He is also believed to have written a work entitled Magica (Mαγικά), as well as one entitled Life of Empedocles. It is believed that Xanthus had some knowledge of Persian traditions, and it is plausible that he, a Lydian, would write about Persian religion, but it seems unlikely due to the available evidence., His seat was believed to be at Sardis, the capital. A contemporary and colleague of Herodotus, most of his writings concerned the lineage and deeds of the Lydian kings. Xanthus was known for writing in the traditional Ionian style of trying to establish the scene of popular myths. One example of Xanthus using this type of writing style is when he placed the scene of the "giant's punishment" in Katakekaumene. Xanthus was also known for adapting historical events that were often considered boring into passages that the general Greek public would enjoy. Xanthus was one of the chief authorities used by Nicolaus of Damascus.

Xanthos (Lycian: Arñna, Greek: Ξάνθος, Latin: Xanthus, Turkish: Ksantos) was the name of a city in ancient Lycia, the site of present-day Kınık, Antalya Province, Turkey, and of the river on which the city is situated. The ruins of Xanthus are on the south slopes of a hill, the ancient acropolis, located on the northern outskirts of the modern city, on the left bank of the Xanthus, which flows beneath the hill. A single road, Xantos yolu, encircles the hill and runs through the ruins.
Xanthos is the Greek appellation of Arñna, a city originally speaking the Lycian language. The Hittite and Luwian name of the city is given in inscriptions as Arinna (not to be confused with the Arinna near Hattusa). Xanthos is a Greek name, acquired during its Hellenization. The Romans called the city Xanthus, as all the Greek -os suffixes were changed to -us in Latin. Xanthos was a center of culture and commerce for the Lycians, and later for the Persians, Greeks and Romans who in turn conquered the city and occupied the adjacent territory. After the fall of the Byzantine Empire in the 15th century, the region became Turkish. The ancient city had long since been abandoned.
