Ženjak (pronounced [ˈʒeːnjak]) is a settlement in the Municipality of Benedikt in northeastern Slovenia. The area was part of the traditional region of Styria. The municipality is now included in the Drava Statistical Region.
In 1811, a hoard of 26 Early Iron Age bronze Negau helmets was discovered in the nearby woods. The village of Ženjak was of great interest to German archaeologists during the Nazi period and was briefly renamed Harigast during World War II.
