Denis Auguste Duchene (23 September 1862 – 9 June 1950) was a French World War I general.

During the Third Battle of the Aisne (the Blücher-Yorck phase of the German spring offensive), Duchêne's group held the high ground of the Chemin des Dames.

However, he was openly contemptuous of General Philippe Petain's order to maintain a defence in depth, preferring instead to consolidate his troops in the front line.

The German armies poured through, taking 19 kilometres in three days, and putting Paris within their reach.

[1] Duchêne was relieved of his command by French prime minister Georges Clemenceau on 9 June 1918.
