Alleins (French pronunciation: [alɛ̃s]; Occitan: Alen) is a commune in the Bouches-du-Rhône department in the Provence-Alpes-Côte d'Azur region of southern France.

In April 1545, during the wars of religion, Alleins was pillaged by troops of Paulin de la Garde under the direction of Jean Maynier, the lord of Oppede and first president of the Parliament of Aix.

The committee in charge of monitoring the implementation of laws devoted much of their time to reading, copying, and discussing their scope thus contributing to the political and democratic education of citizens.

In their primary mission, to arrest suspects, they were very cautious and legalistic unlike the tyrannical reputation of these committees.

After investigation, a committee member after meeting the Représentant en mission Maignet spared any untoward consequence for the commune.
