Wenvoe (Welsh: Gwenfô) is a village, community and electoral ward between Barry and Cardiff in the Vale of Glamorgan, Wales. Nearby are the Wenvoe Transmitter near Twyn-yr-Odyn and the site of the former HTV Wales Television Centre at Culverhouse Cross which is now a housing estate. It is home to the Wenvoe Quarry and Wenvoe Castle Golf Club.

Maintaining a thriving farming community for centuries, Wenvoe, while still a farming village to an extent, has doubled in population in the last hundred years due to new housing developments.

The village originally developed around the parish church of St. Mary, which can be traced back to the twelfth century with the adjacent locality now being a conservation area. Wenvoe is recorded as having belonged to the De Sully, le Fleming and Malefaunt famililies in the later medieval periods. After being escheated to the crown the castle of Wenvoe belonged successively to the Thomas, Birt and Jenner families. Major development occurred in the 1770s but much of this was obliterated by a fire in 1910. Some medieval or earlier fortification is also known to have existed in the wooded hillside at Wrinstone.

On August 15, 1952, the Wenvoe transmitting station broadcast television to Wales for the first time.

An electoral ward with the same name exists. The total ward population taken at the 2011 census was 2,659, though in 2022 the neighbouring community of St Nicholas and Bonvilston was transferred to a new ward.

Mary Immaculate High School is a Roman Catholic secondary school in Wenvoe, although it is administered by the neighbouring Cardiff local education authority, and most of its pupils are from the city.

Gwenfo Church in Wales Primary School is located in Wenvoe.

The village has a village shop with a post office, a parish church, primary school, hotel, a part-time library, barber and three village halls.
