Idris (I) ibn Abd Allah, also known as Idris the Elder, was a Hasanid and the founder of the Idrisid dynasty in part of northern Morocco, after fleeing the Hejaz as a result of the Battle of Fakhkh. He ruled from 788 to 791. He is credited with founding the dynasty that established Moroccan statehood and is regarded as the "founder of Morocco".

The Idrisid dynasty or Idrisids were an Arab Muslim dynasty from 788 to 974, ruling most of present-day Morocco and parts of present-day western Algeria. Named after the founder, Idris I, the Idrisids were an Alid dynasty descended from Muhammad through his grandson Hasan. The Idrisids are traditionally considered to be the founders of the first Moroccan state, setting the stage for subsequent dynasties and states centered in this region. Their reign played an important role in the early Islamization of Morocco and also presided over an increase in Arab immigration and Arabization in major urban centers.
