Registered historic parks and gardens in Cardiff

The City and County of Cardiff is a county in the south of Wales. It covers an area of 140.3 km2 and in 2023 the population was approximately 359,512. Cardiff is the country's capital and hosts its parliament, the Senedd, and a large number of national institutions such as the Wales Millennium Centre, the National Museum, the national stadium of Wales and the St Fagans National Museum of History.

The Cadw/ICOMOS Register of Parks and Gardens of Special Historic Interest in Wales was established in 2002 and given statutory status in 2022. It is administered by Cadw, the historic environment agency of the Welsh Government. It includes just under 400 sites, ranging from gardens of private houses, to cemeteries and public parks. Parks and gardens are listed at one of three grades, matching the grading system used for listed buildings. Grade I is the highest grade, for sites of exceptional interest; Grade II*, the next highest, denotes parks and gardens of more than special interest; while Grade II denotes nationally important sites of special interest.

There are 18 registered parks and gardens in Cardiff. Three are listed at grade I, five at II*, and ten at grade II. Sophia Gardens, Cathays Park, and Bute Park and the grounds of Cardiff Castle originally formed the castle estate. Pontcanna and Llandaff Fields run north from the centre, forming a very large public park. There are five smaller urban parks, six gardens to formerly private houses, the grounds of a hospital and a cemetery. A large number of the registered parks were designed by Andrew Pettigrew and his sons. Pettigrew came to Cardiff from his native Scotland in 1873, as head gardener to John Crichton-Stuart, 3rd Marquess of Bute. Over the following 60 years, he and his sons worked on most of the city's major parks; the Glamorgan Archives, which hold the records of Cardiff County Borough Council containing materials relating to the development of the city's parks, describes them collectively as "the family who landscaped Cardiff".
