Iordanou

Iordanou is a Greek surname derived from the name of the Jordan River, which itself originates from the Hebrew verb יָרַד (yaraḏ) meaning "descend" or "flow down." The river appears prominently in the Bible, and the name was adopted by Christians in the Eastern Mediterranean as a personal name, later evolving into a surname. Morphologically, Iordanou is a patronymic form, meaning "son of Iordanis," which is a Greek variant of the biblical name.

The surname is most commonly found in Greece and Cyprus. Among notable bearers are Christos Iordanou (born 1998), a Greek professional basketball player, and Constantine P. Iordanou (1950–2024), a Cypriot-born American businessman who served as chairman and CEO of Arch Capital Group. The patronymic ending -ou is characteristic of Cypriot and some Greek surnames, marking it as a genitive form equivalent to "-opoulos" or "-ides."
