Sveta Jelena (Croatian pronunciation: [ˈsveta jeˈlena]; English: Saint Helen) is a historic medieval site in Međimurje County, northern Croatia.
Originally a distinct settlement, Sveta Jelena is part of the Šenkovec municipality, about two kilometres away from Čakovec to the north.
The monastery itself was founded by Stephen II Lackfi, Lord of Međimurje and Ban of Croatia, on 27 August 1376 and dedicated to Blessed Virgin Mary and All Saints.
After Joseph II, Holy Roman Emperor and the King of Croatia abolished the Paulists' provinces in his Empire on 7 February 1786, the members of the Order left Sveta Jelena.
Partial archaeological excavations have been carried out recently by the local Međimurje County Museum in Čakovec.
