Larbaâ Nath Irathen (Kabyle: Larebɛa n at Yiraten, or in Tifinagh, Arabic: الأربعاء ناث اراتين) is a town in Tizi Ouzou Province, in the central part of northern Algeria.

French-aligned forces under Marshal Jacques Louis Randon defeated Kabyle defenders of the town as part of a campaign to curb Kabyle independence and bring them under the control of French Algeria.

Randon won the battle, but suffered 400 dead and 800 injured; Kabyle losses are unknown.

Each village had its share of martyrs but what distinguishes this commune is that it gave more than five leaders to the North African Star pro-independence organization.

All these officials are from Ait Oumalou who was part of Larba Nath Irathen at the time.
