The Constitutional Union (Arabic: الاتحاد الدستوري; Standard Moroccan Tamazight: ⴰⵍⵉⵜⵜⵉⴰⴷ ⴰⴷⴷⵓⵔⵜⵓⵔⵉ, romanized: Tamunt Tamenḍawant; French: Union constitutionelle) is a political party in Morocco aligned with the ruling monarchy.

The grouping was founded by then Prime Minister Maati Bouabid in 1983[9][10] and favoured by King Hassan II.

In the 1984 parliamentary election, it won the greatest number of seats, but remained far from an absolute majority.

Later it became an ordinary party without a special role in Morocco's multi-party system.

[11] The party is a full member of Liberal International, which it joined at the latter's Dakar Congress in 2003.
