Penrhyn Avenue is a cricket ground in Colwyn Bay, Wales. The ground was first used by the Glamorgan 1st XI in 1966, although County Championship matches have only been an annual fixture since 1990 (with the exception of 1991 and 1996). In 2015, the ground hosted a County Championship match against Lancashire, during which Lancashire batsmen Ashwell Prince and Alviro Petersen put on a ground record partnership of 501 for the third wicket. The ground was most recently used by Glamorgan in 2019 for a County Championship match, against Lancashire. A proposed game in 2022 was moved to Cardiff and Glamorgan did not play at Penrhyn Avenue in 2023.

The ground has hosted 32 first-class matches and 28 List A matches, as well as several matches in the Minor Counties Championship, both for Denbighshire and the Wales Minor Counties.
