Culverhouse Cross (Welsh: Croes Cwrlwys) is suburban district in the west of Cardiff, capital of Wales, lying on the border with the Vale of Glamorgan.

The busy Culverhouse Cross roundabout is an important part of the primary road network to the west of the city and connects the A4232 (northbound to the M4 motorway Junction 33, and southbound to Cardiff Bay and Cardiff City Centre), the A4050 (to Barry), and the A48 (westbound to Cowbridge and Bridgend, and eastbound to North and East Cardiff). A number of retail parks form around the roundabout and the Copthorne Hotel Cardiff-Caerdydd.

According to place-name etymologist Deric Meidrum John, there has been a crossroads at Culverhouse Cross for some centuries, originally at the intersection of the Cardiff to Cowbridge turnpike and the road between the parishes of St Fagans and Wenvoe. He states that a farmhouse by the name Culverhouse existed nearby and that the word Culver refers to a pigeon. The Welsh equivalent name Cwrlwys was apparently recorded in 1776. Research at British History Online shows that the word Culverhouse may also refer to a dovecot. The Coedarhydyglyn estate, seat of numerous local prominent men from 1767 onwards, is located at the top of the Tumble Hill above the crossroads.
