Xanthippus (/zænˈθɪpəs/; Greek: Ξάνθιππος; c. 525-475 BCE) was a wealthy Athenian politician and general during the early part of the 5th century BC. His name means "Yellow Horse." He was the son of Ariphron and father of Pericles. He is often associated with the Alcmaeonid clan. Although not born to the Alcmaeonidae, he married into the family when he wed Cleisthenes' niece Agariste, and would come to represent their interests in government.
