Allerheiligen bei Wildon (German: [ˌalɐˈhaɪ̯lign̩ baɪ̯ vildoːn]) is a municipality in the district of Leibnitz in Styria, Austria.

Archeological findings on the nearby Buchkogel and Kögelberg mountains indicate that the area was already settled in the stone age.

Findings within the borders of the modern municipality indicate significant settlement activity around the first century AD.

Through the ensuing abolition of feudal structures, important functions previously held by the lords of the castle were transferred to the newly created municipality.

Today, Allerheiligen is a flourishing village or small town in the exurbs of Graz which continues to attract new inhabitants while retaining its traditional rural charm.
