Semič (pronounced [ˈseːmitʃ]; German: Semitsch,[2]: 14  formerly also Semenič[citation needed]) is a settlement in southeastern Slovenia.

In the 1980s the improper handling of PCB waste material led to serious pollution of nearby Krupa Creek and caused a major environmental scandal.

[7] The settlement was first mentioned in the 13th century, when White Carniola down to the Kolpa River was colonised by Slovene and German (Gottschee) peasants.

[8] The Semič parish church is dedicated to Saint Stephen and belongs to the Roman Catholic Diocese of Novo Mesto.

Incorporated into the Habsburg monarchy, it was attacked by Ottoman forces several times; the settlement and its fortified church were completely destroyed in 1547 With Carniola, Semič became part of the Kingdom of Serbs, Croats and Slovenes (Yugoslavia) in 1918.
