The cemetery was established next to a
dressing station established by the
Canadian Field Artillery during the
Second Battle of Ypres, on farmland which was unnamed on pre-war maps; the dressing station was operational from early 1915 until 1918. The name "Essex Farm" commemorates the
Essex Regiment, perhaps because a soldier of the 2nd Battalion of the Essex Regiment was an early interment there in June 1915. Twenty eight members of the 11th Battalion of the Essex Regiment were also buried there during 1916. A monument in the cemetery commemorates the composition of the
war poem In Flanders Fields which is reported to have been written in May 1915 by
Lieutenant Colonel John McCrae MD, after witnessing the burial of his friend, Lieutenant Alexis Helmer, of the 2nd Battery, 1st Brigade Canadian Field Artillery, at Essex Farm; Helmer's grave is now lost. ==Notable burials==
