Achiet-le-Grand (French pronunciation: [aʃjɛ lə ɡʁɑ̃]) is a commune in the Pas-de-Calais department in northern France.

[3] A farming village located 12 miles (19 km) south of Arras, at the D7 and D9 road junction.

In 1871 it got a secondary rail connection to Bapaume, later extended to form the Achiet–Marcoing railway.

The commune was involved in the theatre of operations of the Battle of Bapaume (1871), during the Franco-Prussian War.

The village was twinned with Kings Langley in Hertfordshire, England in November 2009, in honour of Christopher Cox VC from that village who won a Victoria Cross in fighting near Achiet-le-Grand in World War I.
