The Arrondissement of Mouscron ({{Langx|fr|Arrondissement de Mouscron}}; {{Langx|nl|Arrondissement Moeskroen}}) is a former arrondissement in the Walloon province of Hainaut, Belgium. It is not a judicial arrondissement. Its municipalities are a part of the Judicial Arrondissement of Tournai.

The arrondissement was created in 1963 after several municipalities were transferred from the Dutch-speaking province of West Flanders to French-speaking Hainaut following the language laws of 1962.{{Cite book |last=Law |first=Gwillim |url=https://www.worldcat.org/oclc/910103003 |title=Administrative subdivisions of countries : a comprehensive world reference, 1900 through 1998 |date=2011 |isbn=978-1-4766-0447-3 |location=Jefferson, N.C. |pages=50 |oclc=910103003}}{{Cite book |last=McRae |first=Kenneth D. |url=https://books.google.com/books?id=YdvlGrzq87QC |title=Conflict and Compromise in Multilingual Societies: Belgium |date=1983 |publisher=Wilfrid Laurier Univ.
