Dontrien (French pronunciation: [dɔ̃tʁijɛ̃]) is a commune in the Marne department in north-eastern France.

On its territory, Dontrien has two rivers, Suippe and Py, which are full of fish.

There are different possible origins for the name, such as "don de rien" ("gift of nothing"), i.e. a gift given during the Middle Ages from a Lord to one of his vassals at a time when Dontrien was a forest with no land suitable for cultivation.

Of these 107 people there were 21 firemen, 1 station master, 3 wardens, 1 brewery, 1 bakery, 1 café, 12 farmers and 1 nurse.

Émile Zola briefly mentioned Dontrien in his novel La Débâcle, set around the time of the Franco-Prussian war:
