Audun-le-Tiche (French pronunciation: [odɛ̃ lə tiʃ]; German: Deutsch-Oth; Luxembourgish: Däitsch-Oth) is a commune in the Moselle department in Grand Est in northeastern France.

Nowadays, these two cities are respectively named Deutsch-Oth and Welsch-Oth in German.

The history of mining in Audun-le-Tiche and its decline has been described in the writings of Aurélie Filippetti.

The company headquarter later moved to nearby Luxembourg, and in 1801 to Mettlach, Germany.

Audun sister town is Gualdo Tadino in Italy, from which immigrants came working in mining industry during the 19th century.
