Rebel Alliance starbird

The Rebel Alliance starbird, also known as the Alliance crest, was a symbol of the Alliance to Restore the Republic. The flight helmets of the Rebel X-wing pilots were adorned with the starbird logo. Nearly thirty years after the Battle of Endor, the Resistance adopted the same emblem. Many pilots, including Poe Dameron, wore helmets featuring the logo. The New Republic insignia also had the starbird.

It was created by combining the personal signature of Mandalorian artist Sabine Wren and the three-pronged symbol used by Saw Gerrera.
