Llandaff and Barry was a county constituency centred on the towns of Llandaff and Barry in Wales. It returned one Member of Parliament to the House of Commons of the Parliament of the United Kingdom.
The constituency was created for the 1918 general election. Initial proposals were to call the division "Llandaff" but there was opposition from local representatives of Barry and Glamorgan.[1] The constituency was abolished for the 1950 general election.
