Hollie Smith joined the Bluebirds in 2021 from Cardiff City Ladies.
The defender has played in the heart of defence for most of her career to date, but has also impressed in a wing-back role, providing invaluable versatility to the squad.
Iain Darbyshire, Head of Women's & Girls' Football at Cardiff City Football Club: “Hollie is an excellent defender and offers real balance to the side because she is very strong with both feet. Her spell at the Club has been really successful so far and we're looking forward to continuing to work together."
