Cycling in Cardiff, capital of Wales, is facilitated by its easy gradients and large parks. In the mid-2000s between 2.7% and 4.3% of people commuted to work by cycling in the city. In 2017 12.4% of workers cycled to work at least 5 days a week. However, cyclists in the city are deterred from cycling by poor facilities and aggressive traffic, according to research by Cardiff University.

As the busiest city, Cardiff is statistically the most dangerous place to cycle in Wales. Between 1999 and 2008, 1,000 cyclists were injured on the road, 20% of all cycling accidents in Wales, although the number of injuries to cyclists continues to fall.

The Cardiff cycle network is over 58 miles (94 km) long with an additional 3–6 miles (5–10 km) completed each year.

Cardiff is the capital and largest city of Wales. Cardiff had a population of 383,919 in 2024 and forms a principal area officially known as the City and County of Cardiff (Welsh: Dinas a Sir Caerdydd). The city is the eleventh largest in the United Kingdom. Located in the southeast of Wales and in the Cardiff Capital Region, Cardiff is the county town of the historic county of Glamorgan and in 1974–1996 of South Glamorgan. It belongs to the Eurocities network of the largest European cities. A small town until the early 19th century, its prominence as a port for coal when mining began in the region helped its expansion. In 1905, it was ranked as a city and in 1955 proclaimed capital of Wales. The Cardiff urban area covers a larger area outside the county boundary, including the towns of Dinas Powys and Penarth.
