Arlon-Marche-Bastogne was a parliamentary constituency in Belgium used to elect members of the Walloon Parliament from 1995 until 2019.
It corresponds to the arrondissements of Arlon, Marche-en-Famenne and Bastogne.
A January 2018 decree merged both Luxembourg constituencies (Arlon-Marche-Bastogne and Neufchâteau-Virton) into one.
