Auchel (French pronunciation: [oʃɛl]; Picard: Auchez) is a commune in the Pas-de-Calais department in the Hauts-de-France region in northern France.

An ex-mining town, nowadays a light industrial & farming commune, situated 8 miles (13 km) southwest of Béthune and 34 miles (55 km) southwest of Lille, at the junction of the D183 and the D183E roads.

Following the discovery of coal deposits in the area in 1851, the town grew as the demand for coal increased in France.

The coal recession in the late 1960s lead to a constant decline in population, despite the efforts of the municipality to attract and keep people here during and after the recession.
