Caerau is Welsh in Origin.

Caerau is a Welsh place-name adopted as a given name, derived from caer meaning fort or fortified settlement plus the plural suffix -au, yielding the sense forts or ramparts. The element caer is central in Brythonic toponymy and appears widely in Iron Age and Roman sites across Wales; Caerau names several districts and hillforts, notably in Cardiff and Bridgend. The name therefore carries connotations of protection, heritage, and enduring strength.

As a first name, Caerau is very rare and largely modern, emerging alongside a resurgence of Welsh-language names in the late 20th and early 21st centuries; it is used for all genders. There are no standard variants or anglicized spellings; some view Caer (singular) as a related form, and the nickname Cae may occur informally. The caer- element also surfaces in place-names such as Caerleon and Caernarfon, highlighting the name’s deep cultural roots while leaving Caerau a distinctive, evocative choice.
