The Battle of Mărășești was the last major battle fought by the Central Powers against the Kingdom of Romania and Russia on the Romanian front during World War I. Romania was mostly occupied by the Central Powers, but the Battle of Mărășești kept the northern region of the country free from occupation.

The 1917 Romanian Campaign consisted in three battles between late July and early September 1917, fought between Germany and Austria-Hungary on one side versus Romania and Russia on the other. Romania emerged from this campaign with a slight net territorial gain and won its most important battle during the First World War.
