What is the name of the Assassin order founded in Assassin's Creed Origins?

The Hidden Ones are the Assassin order founded in Assassin's Creed Origins.

Bayek and Aya establish the Hidden Ones during the events of Origins, which is set in Ptolemaic Egypt. The organization is created in response to the Order of the Ancients, a secret group seeking political influence and control. The Hidden Ones become the historical predecessor of the later Assassin Brotherhood.

Origins therefore presents an origin story for the series' central organization. Its members adopt concealed identities, operate from hidden bases, and oppose the Ancients' attempts to manipulate rulers and institutions. The group's earliest period is shown before the familiar medieval creed and symbols fully develop.

The Order of the Ancients is the main opposing organization in Origins, so it is a common mix-up. The Order of Assassins is also a historically associated phrase, but it is not the name used for the newly founded group in the game. The later Brotherhood name belongs to a subsequent stage of the fictional organization.
