Matlock is the county town of Derbyshire, England. It is situated at the south eastern edge of the Peak District. The town is twinned with the French town Eaubonne. The former spa resort Matlock Bath lies immediately south of the town on the A6. The civil parish of Matlock Town had a population in the 2011 UK census of 9,543. The population of the wider Matlock urban area is approximately 20,000 (including Darley Dale, Tansley, Hackney and Matlock Bath). The Matlock area is considered to include Wirksworth, owing to the close proximity of the towns. This would bring the area's population closer to 30,000.
